Have you read the Sonatype CLA? The contributor keeps retains copyright and 
Sonatype is granted the license. Much the same way the Apache or Eclipse CLAs 
work. We changed that a long time ago when Brett pointed it out. Additionally 
Hervé and Kristian signed the CLA. It's not just Sonatype employees.

So you had to get approval from all contributors before switching toEPl-only?

Which is another reason why I consider a fork to apache-extras a good idea. And 
don't come me with the argument that the Maven community is not able to 
maintain Maven without your help. At least there IS now a CI environment. And 
remember who built the git stuff on which your whole company is based upon?


I'm not sure what you're referring to, we don't even sell anything with git in 
it. m2eclipse has an m2eclipse-egit connector but we stopped using jgit-simple, 
if that's the work you're referring to, and use the JGit APIs directly now[1].

The argument is not that we cannot fix it becaues we are dumb little bunnies, 
but because the code is not under our control anymore!


I specifically said that folks here, from empirical observation, do not have 
the time or energy. Additionally I would say you don't have much experience in 
the Aether and Sisu codebases.

I most definitely did not say you were dumb, or didn't have the aptitude. But 
having the aptitude still puts you a long way from working with the code 
effectively. There's nothing magical about it, it's the same as any other body 
of code in that it takes time, and energy to learn and gain experience with a 
new codebase and become effective with it.

Humm, guess there are only 3 options left in this

case



1.) We wait 7 weeks or whatever time it takes (most

probably it _will_ take more)


Not likely, it will probably be shorter as I was being
conservative. The scheduling at Eclipse is like a clockwork.
Once the review period of over the creation review is
immediately scheduled. The creation review and initial legal
review will have no issues because nearly 100% of the code
was written by Sonatype employees and we're all cleared at
Eclipse. The code will start the parallel IP immediately and
probably clear IP review very fast given it's all Sonatype
code and there is already precedent for a lot of our code
going into Eclipse.

2.) You ship an ALv2 licensed version of Aether and

Sisu which we can incorporate into an upcoming maven-3.0.4.


The proposals are posted, I'm not changing the licenses
now.

3.) We fork the last ALv2 licensed Aether version back

to the Maven project and fix the bugs ourself.


I believe this will never happen and you will put the
project in a very bad place if you attempt to do that. Since
our last release not a single Maven committer outside of
Sonatype has made any bug fixes or patches to the core (Paul
made one small feature addition). You guys are talking about
a new wagon, POM5 formats, new logging, artifact lookup
indirection, but the day to day of actually patching and bug
fixing is entirely absent and things like the plugin ITs are
failing day after day in CI. Looking at the situation
empirically, the probability that you will have the time and
energy to try and patch Aether and Sisu given no one has
patched any of the normal core code here I find a highly
impractical and dangerous proposal.

Path 1) doesn't preclude your participation and we've done
nothing to hinder Kristian or Herve from participating.

Before we ship 3.0.4 I'd like to fix the SCM

postfix problem which exists in lots of DSCMs.

Will do this

in the next week.


You probably have 6-7 weeks before an official

3.0.4

release would be made so you have plenty of time.

If you are going to wait for Aether and Sisu to

be

provisioned at Eclipse then the total time for

both of those

to pass into that state is about 7 weeks. The

build I

proposed could not be an official release until

such a time

because there are fixes which rely on Sisu and

Aether which

are important for users.

I'll assume that this is fine and no

Maven PMC,

Benjamin and I would like to make a

distribution

available that addresses several issues

with the

all

bugfixes that

do not involve Eclipse Aether[a] and

Eclipse

Sisu[b] as

their incorporation into the mainline and

an

official

release is your decision.


We haven't pushed any individual

artifacts to

Maven

Central as part of creating the

distribution, we

have only

created the distribution itself. If there

is

anything you

want changed let us know and we'll change

it, but

we wanted

to make these fixes available in a build

for users

who are

having problems. We're not trying to

represent it

as

anything other then a distribution that

incorporates fixes

users need.

[MNG-5135][6] Regression: in some

Our achievements speak for themselves.

What we

have to keep

track
of are our failures, discouragements and

doubts.

We tend to

forget
the past difficulties, the many false

starts, and

the

painful
groping. We see our past achievements as

the end

result of

a
clean forward thrust, and our present

difficulties

as

signs of decline and decay.

People develop abstractions by generalizing from

concrete

examples.
Every attempt to determine the correct abstraction

on paper

without
actually developing a running system is doomed to

failure.

No one
is that smart. A framework is a resuable design,

so you

develop it by
looking at the things it is supposed to be a

design of. The

more examples
you look at, the more general your framework will

be.
