Objet : News on the Maven front
 

Hello,

Since Torsten has sponsored the new versions of maven-repo-helper (1.1) 
and maven-debian-helper (1.0), I would like to show you how to package 
software built with Maven in Debian.

It's actually quite easy, since Maven gives lots of information about a 
project, in particular its list of dependencies. So if your project has 
already all its dependencies packaged for Debian, and with the correct 
Maven metadata, then it's a piece of cake!

So for example I want to package Jakarta Commons Exec. I search for the 
SVN url pointing to the latest release of this library in the project 
pages, find 
http://svn.apache.org/repos/asf/commons/proper/exec/tags/EXEC_1_0_1/, 
then I run:

 > mh_make 
--from-svn=http://svn.apache.org/repos/asf/commons/proper/exec/tags/EXEC_1_0_1/

Environment variable DEBLICENSE not set, using GPL-3+ by default

That's it. Now I have a debian folder, and it contains changelog, 
control, rules, copyright and a few other files. My package is ready! 
Ok, I need to file an ITP, fix the copyright, the watch file was not 
generated because the download url does not contain an easily 
recognizable version, but most of the job is done. The package can be 
installed, there is even a documentation package, and all is in the 
proper place.

mh_make should works on most upstream sources packaged with Maven 2, and 
there is even this neat option, --from-svn, where it can download the 
sources for you and build sometimes the watch file.

If you have issues with an upstream package or want improvements, don't 
hesitate to file a bug report.

Cheers,
Ludovic
