Concerns About Pushing Clojure 1.0.0 to Maven Central Repo?

[Stefan Hübner]

Hi all,

Since Clojure now has a stable 1.0.0 I would like to take a step
forward and push it to Maven's Central Repo at http://repo1.maven.org/maven2/.
This would allow people using Maven to integrate Clojure more easily,
since no 3rd party repo wouldn't be involved anymore.

I'm going to follow these guidelines:
http://maven.apache.org/guides/mini/guide-central-repository-upload.html.
But before I'll proceed, I would like to make sure, that there a no
concerns about doing so. If anyone is concerned about pushing Clojure
into Central, please give me some feedback.

If you're OK with the idea, I will alter the distributed POM slightly
to meet the guidelines. The modification is about the missing scm-
part. POM and clojure-1.0.0.jar would then go into the upload bundle
and would be submitted to the Upload Team. Should I add clojure-1.0.0-
sources.jar as well?

The modified POM will look like this:


http://maven.apache.org/POM/4.0.0";
 xmlns:xsi="http//www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://maven.apache.org/POM/4.0.0
http://maven.apache.org/maven-v4_0_0.xsd";>
4.0.0
org.clojure
clojure-lang
clojure-lang
1.0.0
jar
http://clojure.org/

Clojure core environment and runtime library.

repo




  scm:svn:http://clojure.googlecode.com/svn/tags/1.0/
  http://code.google.com/p/clojure/source/browse/




Are there any suggestions or concerns about the bundled files or the
POM (or the idea to push Clojure to Central altogether)?

Thanks for any feedback,
-Stefan

OK, I would bundle clojure-slim.jar too. I'm not familiar with it, though

Will be bundled.

Re: Concerns About Pushing Clojure 1.0.0 to Maven Central Repo?

[Stefan Hübner]

OK, I've got it. Thanks, Laurent!

I would bundle clojure-slim.jar as a "classified" clojure, like Maven
calls it. So the final filename would be "clojure-lang-1.0.0-slim.jar".

To use this one instead of clojure-lang-1.0.0.jar, the following
dependency needs to be declared:


  org.clojure
  clojure-lang
  1.0.0
  slim

Very good point! That's exactly the kind of feedback I was hoping to
get. Pushing a library to Maven Central isn't easy to rewind, if it's
possible at all. So I want to make sure beforehand, that the right thing
is going to get there.

So, here's my explanation, and I hope it is reasonable:

I just used the artifactId which is defined in the pom.xml
shipped with Clojure since r502 (2007-10-30). Why "clojure-lang" was
chosen in favour of just "clojure" confused me too, so I can not give a
good explanation. Maybe Rich or the original contributor can?

But, since Clojure has shipped this artifactId for 18 months now, it has
materialized in many people's repo like that, I guess. In fact, the
official 1.0 distribution "clojure-1.0.0.zip" has been shipped with this
pom.xml. It seems a matter of fact, that in the maven world Clojure
sails under the "clojure-lang" flag since day zero.

So I refused to change that quasi-standard, as I don't want to confuse
other people, who got used to "clojure-lang" in their maven world.

What shall we do then?

To be precise here, there's no such maven script that creates
"clojure-lang", neither does Maven do anything during Clojure's build
process. The pom.xml is created by Ant too.

I second your notion. I guess Howard Lewis Ship ought to get involved
here too, since he maintains the continuous builds and seems to have his
own build scripts, as long as I'm right. Are they monitoring this
thread?

I agree with your position. So, along with uploading the bundle to
Central, I'll provide a patch to reflect pom changes in SVN.

I'm going to push the bundle forward during the weekend.

Since clojure-slim is not bundled in the distributed ZIP for 1.0.0, I'm
going the build all three libraries from SVN tag "1.0" (r1365).

I've figured, though, that the resulting libraries contain class files,
which are of different size than those found in the distributed
clojure-1.0.0.jar. How can this actually happen? Is this problematic?
My build environment was Debian squeeze, SUN J2SE 1.6.0_13, Ant 1.7.0,
OS character encoding UTF-8.

Eventhough I do not have an explanation for the different build results,
building from a fresh /svn/tags/1.0 should be OK, shouldn't it?

It didn't occur to me yet, that having clojure-contrib in the same
group would render "org.clojure:clojure" a bad choice as
groupId:artifactId for clojure itself. Does your suggestion follow a
particular recommendation or policy?

Thanks for the tip! I'm gonna use a genuine JDK 1.5 then.

Right! I am hoping, that Howard will shade some light on his view. I'm
really interested in all decisions regarding the Maven bundle to be as
transparent as possible. Since people will ask why the artifact has
been given a certain ID, I hope, this thread will document those
decisions for future reference. Thus, Howard's (and Rich's too)
opinion and explanation is be highly appreciated.

So uploading the bundle is going to be deferred for a couple of days.

That's exactly how Maven does it too. So there will be no broken patterns.

I haven't heard of any such artifact yet. Can you name one (just curious)?

For the moment, that's out of scope for me. But true, the pattern must
follow the same rules.

No, there is noch such rule. In fact, there isn't much magic behind
Maven's groupId and artifactId, really. It's just a matter of taste how
you name (by which artifactId is meant) your artifacts within a
group. Their artifactIds are directly reflected in their filenames.

If you wanted to place many artifacts within the same group, though, a
artifactId-nomenclatur would help people to find what they were looking
for. But it's completely up to you to come up with such a convention and
communicate it to the users (in one or another way).

Re: Concerns About Pushing Clojure 1.0.0 to Maven Central Repo?

[Stefan Hübner]

I've submitted the Maven bundle for Clojure 1.0.0 to
http://jira.codehaus.org/browse/MAVENUPLOAD-2464. Processing the request
might take a couple of days.

Once the bundle is uploaded to Central, one of the following two
snippets can be used to declare a dependency to Clojure:



  org.clojure
  clojure
  1.0.0




  org.clojure
  clojure
  1.0.0
  slim


I'll submit patches to reflect the changed POM.

Thank you all for your support!

Patch to update pom-template.xml to reflect changed artifactId

[Stefan Hübner]

Hi,

I'd like to contribute a patch to pom-template.xml that reflects
- the changed artifactId ("clojure-lang" -> "clojure") and
- added scm-section.

This patch is meant to be applied both to branches/1.0 and trunk.

Thanks,
Stefan Hübner

http://jira.codehaus.org/browse/MAVENUPLOAD-2464, promotes Clojure as
"org.clojure:clojure:1.0.0". It hasn't received any atention from the
Upload team yet, but I do hope it gets uploaded within the next
weeks. Maybe voting could speed it up...

Thats probably true. If someone from the core team/contributors has the
resources to set this up, that would be cool. It would speed up
promotion to Maven Central alot (fully automatic) - for future releases.

Clojure 1.0.0 has been uploaded to Maven Central - Finally

[Stefan Hübner]

Hi all,

just a quick update on the Maven bundle: it has finally been uploaded
and is available for your Maven based projects as
org.clojure:clojure:1.0.0:jar (groupId, artifactId, version, type).

Thanks for all voters!

Re: Clojurians in Austria

[Stefan Hübner]

There was a "How to build communities" session at EuroClojure. In
summary:

- Just get going. Find some people (with 3 your already a group), find a
  place (like a pub for starters) and meet. You'll like it!
- Meet regularly e.g. monthly.
- If you want to do some coding and your group grows, find a space
  (Vienna has at least one Hackerspace - metalab - that might work. In
  Berlin we meet at an office of one of our members)
- When the group grows, experiment with different schemes for your
  events. London does Dojos a la
  http://www.ntoll.org/how-to-run-an-awesome-code-dojo.html. Here in
  Berlin we've occasonially had talks, but favour *doing* something
  with code. 4clojure.com has loads of interesting problems to hack on.
- Food and beverages are nice but not the key aspect ;)

Good luck for your endeavour!

Re: ANN ritz 0.4.0 release with nREPL debugger support

[Stefan Hübner]

Hugo Duncan  writes:

How would you fire up a swank server from the REPL?

I'm using the Maven and the clojure-maven-plugin, which has no (yet)
goal for ritz or ritz-swank. But if I could just fire up a REPL and
start the swank server there, that would help for the time being.

Also: the Zi maven plugin has not catched up with ritz 0.4.0. I was
trying to force it to use ritz-swank-0.4.0 but got an exception when
doing 'mvn zi:ritz':

InvocationTargetException: java.lang.RuntimeException: No such var:
debug/breakpoint-list, compiling:(ritz/commands/contrib/ritz.clj:51)

On the REPL this works:

--8<---cut here---start->8---
(require '[ritz.swank.socket-server :as swank])
(swank/start {:port 4005})
--8<---cut here---end--->8---

Works with vanilla SLIME. Cool!

Re: ANN Ritz 0.5.0

Hi Hugo,

I have two questions:

a) Are you planning on updating Zi for this new release?

b) How can ritz-nrepl or (preferably) ritz-swank be embedded in an
application?

I had the same problem a while ago. Putting the JDK's tools.jar on the
classpath solved it.

Thank you for writing this up! With a small correction it works
beautifully:

--8<---cut here---start->8---
(ns my-app
  (:use [ritz.swank.socket-server :only [start]]))

;; previously: ritz.swank/start-server
(start {:server-ns 'ritz.swank.repl})
 ;; optionally takes :host/:port keyword args
--8<---cut here---end--->8---


Now ritz-swank works with a REPL sitting in a Hadoop application JAR.

Thank you so much!
