That idea is indeed excellent ! I am a  dedicated maven user and a novice
erlang writer, so I would be more than happy to have such a tool. I
have written couple of plugins and artifacts, and even a tutorial on
maven. Development of plugins is quite easy if you dont have to delve
too deeply in maven's API which is severely underdocumented.

Easy to do once a common setup is agreed upon. AFAIK, OTP proposes
such a framework with its applications ?

Tricky as you need a central repository to work with for common
artifacts. Easy for custom ones of course.

THat's the real added value of maven

Standard.

Maybe a plugin to (http://cargo.codehaus.org) Cargo ?

Here they are :-)

I have been told that some plugins exist for ruby and native
code. have a look at codehaus. 

BTW, an added benefit I can see to this idea is the possibility that
it could foster wider adoption of erlang in Java/j2ee environments and
more generally in enterprise management systems. I am not a master of
erlang but I am already amazed by the ease with which some tasks are
done in erlang when compared to java or other similar settings. Of
course, concurrency and distribution are known strengths of erlang but
even data handling seem easier. 

May be something could be started ? I am ready for discussion a to
throw some time in.
