I really wanted to exit this discussion - but it's not true *we've*
been providing maven releases since xxx.

Doug's release of 1.9 didn't have maven.
My release of 2.1 didn't have maven (though it did have a discussion on it):
http://www.mail-archive.com/java-...@lucene.apache.org/msg08528.html

AFAIK, people who cared about maven did the work after the fact or something.

iBiblio is how people get artifacts w/o having to configure anything.  It is 
the defacto repository.  We've been publishing to iBiblio for 5 years.  To all 
of a sudden stop b/c a few devs who don't know about Maven and don't use Maven 
don't think it should be supported despite the fact that those who do want it 
are willing to do the work is stupid.

I really don't get all this venom towards Maven.  No one is asking you to do 
anything about it.  Ryan and I will fix it.  Or we won't.  Either way it 
doesn't effect you, so why do you care so much as to say I can't work on it and 
have it in a release?

your comparison has some flaws, while its true there are likely bugs in all
this stuff (and the tests are not 100%), they do in fact have tests.

for the javadocs, it too has tests. when you run the javadocs target, it
verifies several things: and at the end outputs warnings and errors.

maven has nothing.

this is still a serious problem to me, especially if we are going the path
of modularizing lucene, then it will become even more serious in the future.

i'm not trying to 'prevent' maven from being part of the release. I'm trying
to get resolution on this maven issue, for which consensus does not exist.

I get your reasoning, but unfortunately, because you don't understand how

i admit i dont understand how maven works, but it does seem to be a viable
alternative. Just because you don't personally like that alternative,
doesn't mean that its completely invalid.

Seems very doable to me. A couple dudes get together and become the
authority for Lucene/Solr Maven themselves. Apply to Mavens whatever
process, make a website, throw a party, make maven artifacts. In a short
time you will be known as the source of Maven artifacts for Lucene/Solr,
sending out our signed jars to the masses. We don't need to do it. No
one has said anything about the Maven process that locks us into doing it.

Comparing Maven support to code features is insane IMO. We are in the
business of code in my opinion. Code and tagging code as a release - at
most putting the release on the mirrors.

Again, I'm still of the opinion Maven should be downstream.

Does an Indic Analyzer have to be part of the release?  I have no need for it 
and it is optional for a lot (likely most) of people.  It's a pain for me as I 
have no way of knowing that it is really working b/c I don't speak the 
language.  Besides, I don't know if the Unit Tests are comprehensive so there 
could be things broken in it.  Can I choose to not include it if I am the RM?

Solr as source and put them up for download.   Heck, why bother releasing the 
docs?  Some of it isn't always correct and I don't have a way to test that

We've been providing Maven releases since 2005.  That's Lucene 1.2!  
That's pretty much longer than everyone here has been a committer other than 
Hatcher and Otis.  So, yeah, I do think it is removing a pretty big feature.

Again, for the 5th or 6th time, this is why I said the onus is on those who 
want Maven to fix it.   I don't expect you to care about it but that doesn't 
mean you should prevent it from being in the release.   I totally agree that it

To me, the real problem is there does not seem to be consensus that maven is
part of the release process.

For example, you feel it is "defacto part of the release", and that calling
it optional is removing a feature.
Others have mentioned they feel it was always optional, and to be "part of
releasing" needs a vote/some sort of consensus

I already said that personally, if there is a way to verify that it works,
*my* concerns go away. And if i was moving stuff around, or refactoring the
build, or adding/upgrading a dependency, i don't mind at all hacking on some
pom.xml in a minor way until something like 'ant test-maven' succeeds.  But
currently it is the onus of the RM to *eyeball all these xml files* and
determine they are correct.

Still, this is just my personal opinion, and doesn't speak for everyone
else. So what i was trying to do was to get all the options out on the
table: such as maven maintained downstream, maven part of the release, maven
not part of the release, etc.

No, they can't.  They can put them in their own repo, but they can't put them 
in the official ones that are by default baked into Maven (the iBiblio one).

At the end of the day, I don't see what the big deal is.  For those of us who 
want Maven, we need to step up and make it work seamlessly.  Why should you 
care if we do that?  Given it gets fixed, it won't effect you.  I understand

i completely agree with you. I didn't mean to give the impression by "every
month or two" that we should actually have anything remotely resembling a

The "standard" places, (apache / ibiblio / sonatype) require a project
representatives to post artifacts to the repository.  If the artifacts
are hosted at "hotsteamylucene.ru" yes, anyone could post anything.  I
hope we agree it is worth making it easy for people to use lucene via
maven, ivy, or whatever.  We need to make sure this is not a pain, and
maybe split out parts so that the RM does not necessarily need to do
everything.

My understanding is that you would feel OK about this if there was
some automated test that used the artifacts, and that the RM need not
know anything about maven internal -- just copy a directory to
somewhere in apache infrastructure, I don't think this is too far off.

...
: And as far as whether we *need* to release often, i'd like to start looking

Agreed, my point was merely that even if we get to the point where we are 
capable fo releasing off the 3x breanch every month (because we have the 
process/tools down pat) that doesn't mean we should.  we should release 
when we have features that we think are worth releasing, and are stable 
enough to support moving forward along that major branch.

For example: we probably shouldn't bother having a release if the only 
thing commited to that branch since the previous release are to fix some 
typoes in javadocs, or because new tests were added -- those changes are 
good, and worth having, but too much proliferation of minor versions for 
things that don't impact the users can be distracting and confusion, and 
makes it hard to recognize when a release is worth upgrading too (it's a 
girl who cried wolf thing).

The other situation to ocnsider is when a feature is commited which works 
correctly, and has good tests and documentation, but people have 
questions/reservations about wether the API is really what we want -- just 
because the calender says it's time for the quarterly release, and the 
code works, doesn't mean we should just blindly release.  (and yes, i 
realize that for the 3x branch, these API decisions should probably be 
hashed out on trunk before the feature is backported to 3x ... it's not 
hte best example)

In any case, i'm really just trying to bring things back to the point i 
was getting at in my last mail: the decision to release should be made 
based on state of the code, not the calender; but it would be awesome if 
hte process was automated enough that we could release as often as we 
thought the state of the code warranted it.

: I think we should try to avoid massive yearly releases with a ton of changes
: at once.

No argument there ... in the past i think this was really a combination of 
(a) "concerns about API/back-compat" and (b) "the release process is such 
a nightmare let's get a few more features in before we release so we don't 
have to do it again too soon" ... the 3x branch makes (a) a smaller 
concern, if we can make (b) go away we can pretty much release whenever we 
want.

I will quote Ryan here: The "artifacts" are the identical .jar files put
into a special directory structure.

Therefore, if we release without maven, the jar files are signed by our
release key. this is authoritative enough, maven does check signatures
correct?

I'm not buying the authoritative argument, it seems like any old joker can
take our signed jars and put them in maven themselves, without us having to
do any work.

I agree.  But, like I said, if those who want it step up and make it fully 
supported, then there is no more cost than uploading a few extra artifacts, 
then what's the extra cost?  As usual in open source, why don't we just leave 
it those who do the work?  If no one steps up and fixes it, then it doesn't get 
included.

I'm sorry, I don't see the other options.  I think it does need to be done by a 
Lucene committer to be an official Lucene artifact.  OK, well, I suppose some

don't think there are other options.

This "authoratitiveness" comes with a significant cost, that is the
complexity of maven in our release process.  I'm not convinced its worth
this cost, and before we decide to have maven as part of the release, i'd
like for there to be an actual vote.

Sorry to change my tone, but I was under the impression we needed a lucene
committer to do all this releasing work to support maven, it seems that this
is not the case, and other options are available.

Because it's not authoritative.  How would our users know which one is the 
official one?  By publishing it under the ASF one with our signatures we are 
saying this is our official version.  We would never claim that the Solr 
Commons CSV one is the official Commons jar, it's just the official one that

But I'm not sure this is the best solution? If we can push this downstream,
so that the release manager has less to worry about (even with testable
artifacts etc, the publication etc), why wouldn't we do that instead?

Why don't we just leave this as this:

Those of us who want Maven supported as part of the release need to get our 
stuff together by the next release or else it will be dropped.  That means 
making sure the artifacts are correct and easily testable/reproducible.  If we 
can't do that, then I agree, it should be a downstream effort, at least until 
we all realize how many people actually use it and then we revisit it at the

I don't understand this, if I, as a lucene committer, can arbitrarily
publish commons CSV artifacts under maven, without being a commons CSV
committer, then why does someone have to be a lucene committer to publish
maven artifacts?!

Furthermore, if this is possible, then why does lucene itself have to
support maven, if someone else (e.g. hibernate) can simply download our jar
files and do the same?

Typically, this is done by adding the library in question to the release, 
renamed appropriately.  For instance, in Solr, we had a trunk based version of 
Commons CSV at one point, so we put it up w/ the Solr artifacts and had the POM 
reflect that.  But yeah, it can be a pain.

I'm not saying we have to support it, but, in my view, it's pretty hard to take 
back a feature, admittedly only for some, that we have supported for a long 
time.

If somebody reorders the directory structure, I will shout “revert revert 
revert” J

 

We can only “fully” support maven by switching to maven, but most of the core 
committers don’t want this (including me). In my opinion, the approach we had 
was fine, to simply create the jar files as we do for the binary release, but 
add some (hopefully) automatically generated pom files to it.

 

One thing I don’t like in this release process (as it currently works) is 
non-repeatable maven artifact generation. With maven, it’s impossible to 
regenerate the JAR files with the *same* MD5, even the MD5’s of the jar files 
in the binary release zip are different than the maven ones. If repeatability 
is not possible, at least the JAR files in the –bin.zip should be identical to 
the maven released ones!

Producing maven artifacts does not now and will not require source tree reorg.  
If the build itself were converted from Ant to Maven, some reorg would likely 
be required, but there are way too many dead bodies that would have to be 
trampled on before Lucene/Solr Ant->Maven build conversion could happen...

The -SNAPSHOT.jar renaming thing is because that is the only suffix Maven 
recognizes as a snapshot, for which special handling is required, so that the 
latest version is always acquired from the Maven repository by local builds 
depending on Lucene/Solr artifacts.

AFAICT, Maven 3.0 is fairly close to release (in 3rd beta release).  One of the 
goals of this release is maximizing backward compatibility, so I don't think 
this is anywhere near as much of a concern as it was last time around (1->2).  
Here are detailed compatibility notes:



Nothing major there, and in a non-Maven build that just wants to produce Maven 
artifacts, probably no concerns at all (IMHO).

It sounds like maybe we should, since the situation seems ambiguous at the
moment, and there is a lot of different opinions/disagreement.

Though we should make it clear what we are voting on:
1. having the maven stuff in our source code.
2. maven being part of the release process.

As far as #1 goes, to me its just like any other code. We have some other
code already with no tests and I don't think thats reason to remove it from
the source tree, when it can be improved by adding tests.

However, I don't think its acceptable that the release process (#2) is
currently undefined wrt maven. I think we need to get this nailed down, i
think we need a well-defined release process.

It's not quite as bad as the POM template files, since IntelliJ can be told to 
find all dependencies in a directory, rather than explicitly naming every 
dependency, and LUCENE-2611 uses that facility just about everywhere (I think 
the only exception is the JUnit jar test dependency, since the other stuff in 
the same directory shouldn't necessarily be depended on during testing).

So the IntelliJ project files in LUCENE-2611 would continue to work without 
manual intervention in the face of upgraded and/or additional dependencies, but 
would require manual effort to sync up with structural changes.  While I don't 
agree that this is a deal-breaker, since the manual intervention required would 
be fairly minimal, I agree that auto-generation would be a lot more useful than 
the current static approach.

My thought process was that setting this up manually would provide a benchmark 
for auto-generation; the auto-generated version should not be less functional 
than the manually generated one.

For sure... though I also suspect the majority of lucene maven users
are not on the mailing list.  As a maven user, people can just depend
on 'h2 full text' or 'hibernate search' and never worry about what
version of lucene they are using (or even that it is lucene at all)

If so, perhaps you should call a vote?

It is not a first class citizen.  Apparently the last Solr release
went out w/o working maven support.

But it's not quite so black and white either... I see no reason to
*remove* maven related stuff from ant (and it's good if people improve
it), and I've even applied patches to the maven stuff when supplied by
others.

Unfortunately, LUCENE-2611 does not automatically generate IntelliJ setup files 
- they are static, just like the POM template files.  I think it's possible, 
using an Ant BuildListener-extending class, to do automatic generation, but I 
haven't attempted it yet.  I'll open an issue.

I completely disagree.  It's either a first class citizen or it's not and by 
moving it out, you're guaranteeing it will not be consistently right.   I think 
it would be interesting to take a poll as to who uses Maven in the user 
community.

We took the middle road in Nutch - we switched to ant+ivy to manage 
dependencies. This way we get single copies of all deps, and build.xml 
is still recognizable and useful. Of coure, this doesn't solve the 
publishing part of Maven functionality (yet).

Maven has never been a required part of our releases, and I don't
think we should change that.

We should also keep in mind that there's nothing really official about
a "release manager".
There's no reason the person(s) that signed the normal release need to
be the same person that signs the maven stuff (but it should be a PMC
member if it's hosted by the ASF).

If there are people around during a release that want to handle the
maven stuff, that seems fine.  It does *not* have to be the release
manager.  It seems fine to make reasonable accommodations if some are
working on making maven artifacts available at roughly the same... but
if not,  it should not hold up the release.

[karl.wright]

My 2c...

Maven is pretty much incompatible with some of the standards of release 
engineering, namely repeatable builds.  It tries to do pretty much the same job 
that apt does under debian and ubuntu and is therefore not terribly useful in 
that environment.  All the mavenistas I've talked to have no good answer to 
that, except perhaps for setting up local repositories to do what you need.

Another approach that might be worth considering is using ivy instead of maven 
per se.  There is a lot more control that way, and most of the engineers 
familiar with both approaches prefer ivy, if it's an option.

Agreed, but over time, it is lessened by the fact that you already have most 
common files/jars and furthermore, you only have one copy of them instead of 
one under every source tree.  I think, over time, you actually end up 
downloading less than with other approaches and that even includes the 
downloads one gets when Maven upgrades itself.

I don't see how it can be.  You have to be a committer to push it to the ASF 
repository for syndication on iBiblio, etc.  That being said, we really aren't 
that far from a process that we can have confidence in.

The solr sample app is tested -- i don't know anything about lucene demo stuff.

Most of the solrj tests run from the example schema via jetty and embedded.

I should correct myself here.  While all of the above is true, it likely still 
won't work for Lucene b/c the source trees aren't in line w/ Maven conventions. 
 Thus, we will probably still need to output IntelliJ format.  I do, however, 
think it isn't much of a leap to also output a POM file.

Maven is not bad because it's magic - magic is frigging great - I want
my software to be magic - it's bad because every 5 line program from
some open source code/project that I have tried to build with it has
gone on an absurd downloading spree that takes forever because it's
getting many tiny files. This downloading spree never corresponds to the
size of the code base I am working with, and always manages to surprise
by the amount of time it can slurp up.

That's enough for me right there - I've heard others talk of other non
magical things that sound scary, but I won't dig any deeper into this
absurdity. Either I *really* don't like Maven, or no one knows how to
properly set it up - which makes me still not like it. When the magic is
absurd, it loses a little of its magic.

Finally, there is a difference between releasing source code, releasing
signed jars, and signed maven files, and *just* releasing signed jars.
Dropping maven doesn't get you back down to releasing source code. I
still think Maven should be a downstream issue.

Yes.  I know for a fact IntelliJ can read the POMs.  I use it all the time.  Go 
check out Mahout and point IntelliJ at it's POM.  You will be up and compiling  
(in your IDE) in less than 2 minutes give or take.  I imagine Eclipse has 
similar support.

I totally understand it.  I'm not some Maven fanboi (especially as the person 
who used it to put together the Mahout release, initially).  I know it's warts, 
believe me, as I have lived the pain.  That being said, for _most_ users (i.e. 
not necessarily us committers) who are simply using Lucene/Solr within a much 
broader environment of dependencies, having the JARs available in the Maven 
repo w/ correct POM files is a very good thing that makes it so much easier for 
them to do their day to day work and I would hate to see that go away, 
especially since it is something we have supported for quite some time, albeit 
with varying levels of success.

I've been wanting to do those Maven tests for a while now, but simply can't 
find the time relative to my other priorities.  I guess if the community is 
saying that if someone doesn't step up, it's going to be dropped, I'll step up. 
 I can likely commit to it before the next release.

So are you saying, instead of generating IntelliJ configuration, we generate
poms, and then we have a route, via maven, for users to automatically set up
their IntelliJ (and also eclipse?) IDEs?

If so this sounds great to me. Because it would be nice to make the IDE
configuration easier, not just for IntelliJ.

+1. this would resolve all my concerns about maven, because we have a way to
test that it stands a chance of working *before release*.

I hope you don't think I am picking on maven here, I'm equally disturbed
about the demo application, and i think it should have a basic unit test too
that indexes stuff, fires itself up in jetty, and runs a search.

Like maven, i know some people don't necessarily like the demo, but as long
as we are going to ship it, I want tests so that we dont find its completely
nonfunctional after the release. Unlike maven, i think i stand a chance of
actually being able to write the test for this one though.

OK, I get that a lot of committers here don't like Maven and I don't think 
Lucene should switch to a Maven build and it's a pain to do complex things in, 
but I use it all the time for Lucene/Solr (for none complex things) and I know 
of a lot of people in user land who use it as well b/c it makes the common 
things _users_ do really easy.  

And, as much as Hoss restarted this thread by saying the PMC releases only 
source, it simply is not what users expect.  That's why we sign all the 
artifacts.  They are the RM saying I verify this and the PMC then votes on all 
the artifacts and it's why we push them all up for distribution.  Of course, we 
are only required to release source, but you show me a project that does only 
that at the ASF and I'll show you a project w/ very few users.

At any rate, the big problem w/ Maven and Lucene is not that 
generate-maven-artifacts doesn't work, it's that the POM templates aren't kept 
in sync.  However, I think we now have a solution for that thanks to Steve and 
Robert's work to make it easier to bring Lucene into IntelliJ.  In other words, 
that process does much of what is needed for Maven, so it should be relatively 
straightforward to have it automatically generate the templates, too.  In fact, 
it would be just as easy for that project to simply produce POM files (which 
are well understood and have a published spec) instead of creating the IntelliJ 
project files, which are not well understood and not publicly spec'd and 
subject to change w/ every release and simply have IntelliJ suck in the POM 
file since IntelliJ supports that very, very well. 

Then, to automatically test Maven, we simply need to do a few things:
1. Generate the templates
2. Build the Maven artifacts and "install" them (this is a Maven concept that 
copies them to your local repository, usually in ~/.mvn/repository, but it can 
be in other places and it should be clean)
3. Generate a "test" pom that includes, as dependencies all the Lucene Maven 
artifacts and maybe even compiles a small source tree with it

If that last step passes, you know everything is right.  However, short of #2 
and #3, as long as the POM's are being generated accurately, I think I would 
feel comfortable releasing them, whereas I agree, now, with Robert, that we 
probably shouldn't be releasing them now.

(BTW, I love the "Maven is Magic" (and really any "It's magic, therefore I 
don't like it") reasoning for not liking it, whereby everyone complains that 
b/c Maven hides a bunch of details from you (i.e. it's "magic"), therefore you 
don't like it.  At the same time, I'm sure said person doesn't understand every 
last detail of, oh, I don't know: the CPU, RAM, the Compiler, the JDK, etc. and 
yet they have no problem using that.  In other words, we deal with abstractions 
all the time.  It's fine if you don't get the abstraction or don't personally 
find it useful, but that doesn't make the abstraction bad.)

its better not to upload them at all at the moment, since the pom files are

It's good to see what appears to be a maven-positive resolution to this thread. 
 I've gotten to this thread late, but FWIW, I've agreed with basically 
everything Ryan has said, as I am a maven user too.

What would be *really cool* is Hudson automatically uploading the artifacts of 
each build to an apache maven snapshot repo (which I don't think would require 
any public/private key blessing).  This used to be the case in SOLR-586 (thanks 
Grant!) but it has since broke.  I'll file a bug report.

sounds great, i thought this was the idea here:
https://issues.apache.org/jira/browse/LUCENE-2268

I mean, even during normal development, if there was an easy single command
i could run to verify i'm not breaking maven support, this would help,
especially when refactoring / moving things around / etc.
I wouldn't mind running this at all, to try to keep maven functional. I also
wouldn't mind debugging or even trying to figure out bits of maven until i
make it pass.

my problem is just that without any automated verification like this: maven
is just a big scary piece of code with no tests, and I cannot touch it!

To automatically test if the maven files work, we would need to run
maven...  that seems like a non-starter for many people.

We could easily add a maven test project -- but for it to be 'real' it
needs to use maven.  I'll happily volunteer to write it.

If you are worried about the signing part...  can we keep the
maven.dist folder out of the signing task?

I won't speak for anyone else, but the .pom files are signed by the RM's
key.
I checked to be sure, for example:
http://people.apache.org/~markrmiller/staging-area/rc1/maven/org/apache/solr/solr-core/

as stated earlier, i dont want to sign anything that is incorrect.
I know the true purpose of signing, but i'm not willing to put my release
key on these things, unless there is automated testing.

is maven incompatible with unit testing?

I agree with this -- let us make them two tasks.  However can the RM
run the "generate-maven-artifacts" task and put the results somewhere

The "artifacts" are the identical .jar files put into a special
directory structure.  You have already verified they are correct --
this is what I don't want to loose.

I agree the RM does not need to be responsible for saying the pom
files are correct -- this can be checked by whoever actually deploys
them.

The only way to 'test' this would be to have something that uses maven
try to load them -- I would happily add that, but have avoided that
since it opens the toxic maven hate hard.   LUCENE-2493 would make it
pretty easy for others to know if stuff is valid on dev builds.

I can see leaving the build support around for those committers that
like and want to support Maven - I'm sure it wouldn't be easy to rip it
out short term. But I still think it should be completely outside of the
RM's cares (as Yonik claims it is now - I'd like to see a bit of
consensus on it though). The RM does the Lucene release - someone steps
up and does the Maven stuff or they don't.

P.S. Every time I have had to do the Maven stuff, there has been issues
with uploading the files (permissions are always a little off), or other
little things that some dude's maven repo wathcing script pings me about
- even when i follow the release todo to a T. It's annoying and a hassle
to handle these situations - for Solr 1.4.1 I took forever too fix the
Maven repo - first I said: someone who cares about maven please step up
- no one did. Eventually I went and got it done because I felt
responsibility as the RM. Personally, I think all those little issues
should be on some that cares about supporting Maven - it's separate from
releasing the Lucene/Solr bits.

i want to solve 'part 1: verifying artifacts are correct before
signing/uploading at all'.

to me, maven is nothing more than a contrib with no unit tests.

it needs tests so we know it is working.

I understand what you are worried about... and think we can avoid it.
How about:

1. Keep the "generate-maven-artifacts" in the release.  This just
copies the "official" jar files to a special directory structure (same
keys etc)
2. The RM just makes a zip or copies that folder somewhere.  (perhaps
to their own ~people folder)
3. Someone else get that into the repo

I think it is important to *try* to have the "official" jar files in
the maven repositories -- we have scripts that get that mostly right.
In the past when we have errors it is just the pom files that get
edited (these are the files that say what the other files/dependencies
are).  If we remove the "generate-maven-artifacts" task, then without
writing lots of new scripts (uggg) the jar files in the maven repos
will be a different build.

Does that sound OK?

Shortly after LUCENE-2493 was created, I looked into the possibility of having 
Maven treat *-dev.jar files as snapshots.  As far as I could tell, this is not 
a configurable item: snapshots are named *-SNAPSHOT.jar - it's hard-coded in 
lots of places in the Maven code.  I like Maven, but inflexibility like this 
makes it hard to get pre-existing projects to play nice with it...

Note, I am *not* suggesting that maven is the best tool etc etc...
that is not a discussion worth having here.

I am saying that the maven artifacts (pom files etc) generate in
3.x/trunk work well if you are using maven/ivy.  I don't see why we
want to drop that from the release?

Thank you Chris. Actually this does help a lot, more than you think.
I tried to digest these guides and it only reinforced my opinion that I
shouldn't be involved with maven at all.

I don't mean to criticise the maven project by any means, but as a software
developer there are times when you look at something and you say 'this is
way too complicated, it just simply isn't compatible with my brain'. I know
some people prefer ant, some people prefer maven, some people write their
own python scripts and still use emacs, and I'm not trying to say I have
preference over any given system.

I cannot in good conscience sign with my key, nor vote over any maven
artifacts. I noticed these guides only mentioned how to upload (which itself
seems extremely complex). But nowhere do i see 'how do you test that your
artifacts are correct'. And thats really the main problem I have with our
maven support.

I don't care how easy it is to actually upload things (via plugin X or a
JIRA issue). I want to know things are correct before uploading them
anywhere.
So, I think my original statement still stands. I'm happy to volunteer as RM
as long as we realize this means no maven involved. If someone else wants to
take on the 'maven' role, thats fantastic!

If its not acceptable to do a release without being a maven expert, I am
fine with that too. I can contribute in other ways such as improving
automation.

I've heard that about every release of Maven, and any time I've tried
to use it, it doesn't quite work as expected, and given what it does
should be fairly trivial, the fact that there bugs/issues, and it's
been released to me has meant I don't want to use it.  It's like a

[Mattmann, Chris A (388J)]

Hi Robert,

I can help a little here. Check out this guide:

http://maven.apache.org/guides/mini/guide-central-repository-upload.html

The long and the short of it is that there are several canonical Maven repos 
that are sync'ed to Ibiblio and Maven central. Apache has one (through 
repository.apache.org), and other organizations have em' too. In Tika, we 
simply inherit from the top level Apache POM and the Maven release plugin takes 
care of the rest. I'm not sure how to do this with Ant, but am sure it can be 
done (and it might be aided by Ivy).

If you are just doing it when you release, which doesn't happen that often, 
then you could consider just creating a Ticket and uploading the release jars 
through the Sonatype JIRA process, located here:

http://nexus.sonatype.org/oss-repository-hosting.html

Guide is here:

https://docs.sonatype.org/display/repository/sonatype+oss+maven+repository+usage+guide

Hope that helps!

Chris

Well, this is of interest to us too I think. Because (though its not flushed
out) we are talking about possibly Lucene + Solr releases at the same time.

Solr has Tika integration, and even apart from that brings in other
dependencies too, much more than any lucene modules do.

There has to be a way to let the "maven experts" take care of this stuff

My - possibly flawed - understanding is that Maven brings in more users, not 
more devs. A dev needs to know how to build the software package(s) s/he's 
working on.


With PyLucene, for example, I've consistently refused to release binary 
packages as there are just way too many possible combinations of 
Python/Java/gcc/OS versions to do a thorough job.


Building PyLucene isn't exactly trivial on some platforms such as Windows, 
for example. I'm sure this has cost the project some users as the barrier to 
entry is a bit higher than it could be.


On the other hand, the users that remain at least have some understanding 
about how to build and debug a C++ python extension and that's a very good 
thing because a user is more likely to become a dev if they understand how 
to rebuild the software package they want to contribute a bug fix to, for 
example.


That being said, it is rather easy to build Lucene binaries using ant, so 
Maven at first blush doesn't seem to bring much. Where it becomes more 
useful is that in a situation where many dependencies are required before 
a particular project of interest that depends on Lucene can be built, a 
working Maven install takes care of the chore or bringing in all these 
dependencies.


For example, I recently did an experimental build of Tika for Python using 
JCC. Tika's Maven tricks pulled in a very large number - dozens - of 
dependencies that had I had to download and build them all by myself 
manually, I would maybe not have spent that time with Tika to begin with.


Of course, Lucene is quite the opposite. Besides a JDK (and possibly ICU), 
it depends on nothing else. The need for Maven support is less obvious there 
too.


The question about Maven support is then about how hard do we want to work 
to get more users, balancing that with how easy do we want to make it for 
them to become devs, contributors.


I agree with the consensus that seems to be forming. Lucene has plenty of 
users already, many of which are hopefully Maven savvy. They should help 
maintain and improve Maven support for Lucene.

i dont understand why we (apache) need to be involved? why cant someone who
really knows maven do this, and do it right?

since i have been around, it seems the "maven" is wrong in nearly every
release[1] including even bugfix releases.
if i am going to be the one making artifacts, i want them to be right.

As a maven user (not an expert by any means), the maven stuff in
3.x/trunk is actually pretty good.  Running:
  ant generate-maven-artifacts -Dmaven.dist.dir=maven -Dversion=4.0.rxxx
makes a folder (maven) with everything it needs.  This is *very* easy
for maven apps to test against.

What are the deploy steps that we are talking about dropping/changing?


- - - -

As an aside, I still think it is worth changing our dev builds from
"-dev.jar" to "-SNAPSHOT.jar" so that the daily builds are
automatically valid SNAPSHOT builds that are easy for maven/ivy users
to work with.  (LUCENE-2493)  As is, maven users have to checkout and
build with a special version to test/use a dev build -- since this is
more work then many people want to deal with, we find problems with
the maven pom files *after* the official release.

Just my opinion: (personally i do not use maven, nor understand it).

If maven support is beneficial to bringing more devs to lucene, we should
consider what we can do.
But at the same time, perhaps Makefiles would bring more devs, too.

My problem with releasing with maven is that i could not honestly even +1 my
own release artifacts, because i don't know what the hell is going on with
the maven artifacts.

There has to be a way to let the "maven experts" take care of this stuff
somehow, if its really going to be beneficial.

Re: discussion about release frequency.

Just to be a bit more clear: I'm all for ditching the maven stuff from
the src tree as well, and having everything happen post release. But I
can see how that could be a pain in the ass if we did that quickly. I'm
much more concerned that Maven get out of the release process than the
maven poms/build.xml support being ripped out soon.

Well, you have always claimed that as de jure, I think defacto is that
it's part of the release. And the defacto is to follow the 'release to
do' best as makes sense (I'm not sure the Solr release to do wiki always
makes much sense). I've been waiting for the day that you release Lucene

do - but I think most of us feel it's pretty much on the list and this

To clarify - it never really was part of the official release process,
(just as the referenced wiki pages and much on them never were either)
- it was sort of on a release-by-release basis.  We've never

I don't think we really care if the tools remain in Lucene - that will
allow some guy that cares about Maven to still make it all happen.

I think we are more saying, lets drop it from part of the official
release process. When we release, we don't worry about Maven as part of
the release process. We can leave the Maven support tools we have - but
it will be up to someone to step up and handle the Maven part outside of
the official release process. So we drop it from the release todo's and
what not (moving it to another page about how to create the maven
artifacts).

Then those that release and don't want to deal with Maven do not have
to. It won't fall on the RM to think about Maven by default. Mavens
supporters will have to step in.

Maybe, but deprecations shouldn't be the primary motivation for releasing
anyway.

I can't argue with this, I think the first release will be painful, but
thats exactly what I am proposing here, gearing ourselves up for more rapid
stable releases.

And as far as whether we *need* to release often, i'd like to start looking
at whether we *should*.
For a realistic example, Solr 3.x got autosuggest functionality. This isn't
really a disruptive thing, its not going to introduce a lot of deprecations,
etc.
do we *need* to release because of that? no. *should* we release? I think
yes.

To a lot of users, this is a major search engine feature, and they might
consider it more "major" than something we consider "major" like flexible
indexing.
With stable releases, the user can put this feature into production more
easily because all the "sexy" stuff is in trunk, not causing them
upgrade-hell.
This results in a faster feedback process for us, too.

I think we should try to avoid massive yearly releases with a ton of changes
at once.

How do other projects handle this? especially ones that "leave it to
interested users to do the maven releasing", since that sounds like what we
want to do.

as far as LUCENE-2268 not helping much, you might be right, I don't
understand maven at all... but the fact we currently "support" this but have
absolutely no way to test it is wrong.
the other day i was actually looking at ant's xml validation task:
http://ant.apache.org/manual/Tasks/xmlvalidate.html thinking the build could
at least make sure someone doesnt forget a  in these pom.xml files...
even this would be an improvement.

+1 - release managers shouldn't have to be in the love-Maven camp, which seems 
to be mighty small here in Lucene/Solr dev-land.  User-land, however, is likely 
a very different story.

If what you mean is that maven artifact production tools should not be in the 
Lucene/Solr source tree: -1000.  Requiring these to be hosted elsewhere would 
very likely kill Lucene/Solr maven compatibility, and I don't think that's your 
intention.

Maven artifact production under Lucene's/Solr's Ant build suffers from the same 
problem as releasing generally: lack of automation.  Too much manual 
intervention is required to keep the .pom templates in sync, etc.  LUCENE-2268 
would afford confidence in the produced artifacts, but it would do nothing to 
address the current production process problems.

Re: discussion about release frequency.

[Lance Norskog]

+1 on the ant-only policy. I've recently been futzing with Mahout and I 
had not been faced with the scrofulous horror of Maven. Please keep it 
out of the main source tree of solr. You can do whatever you want with 
the internal Apache build process.

maven is such a contentious issue -- people either don't give a shit
about it, or think it's the end of the world if the jars aren't there.

In the past i've argued that enough users care about maven we should
really try to make sure we play nicely, but the more i think about it the
less i think it should be part of the release process.

the ASF releases source code.  When we vote on a release, tha's what we
are voting on: source.  We may also distribute precompiled binary jars
via the download mirrors, or via maven, but that's not what the release is
about -- so let's get hte pom template files out of hte src tree, let's
get the maven related tasks out of the build.xml file and treat publishing
to maven as a seperate process that happens *after* the release.  We vote
on the release, we release it, and then the folks that care about maven
can publish the jars after the fact.

Given how messy and problem plagued the maven releases code is currently, +1
to this idea.

Re: discussion about release frequency.

[Chris Male]

+1 to more frequent releases.  I think we are already seeing 3x being pushed
forward as the stable version for users wishing to do some development of
their own.

I am more than happy to work with whoever on the maven issues as I feel that
it is really important to keep making maven releases.  Maven does have a
release plugin, similar to what you want to build for ant, perhaps that can
provide some inspiration?

+1 here too - I'm all for more frequent releases - not sure how much
time I can put behind that release to release, but I'm all for the idea

Re: discussion about release frequency.

[Michael McCandless]

+1 to simplify the release process / ReleaseTodo wiki, and +1 to
release a 3.1, and +1 to do frequent stable releases.

Having a stable branch gives us that freedom and we should use it!
