Some time ago I embarked on the primitive hackery of Maven in order to
develop a generic tool to support autopkgtests for Maven [1]. I managed
to hack together a proof-of-concept implementation [2], which actually
worked with some of Maven projects I tried.

My idea was to disable the build of "all", remove the sources, patch the
pom.xml to use system-provided JARs and run 'mvn' as debhelper would do.
However, the more Maven projects I tested, the more complicated the
autopkgtest runner grew, to the point I abandoned it.

However, looking back it seems worth revisiting, and I would be very
happy if someone would pick it up and turn it into something usable in
Debian. At least for very simple Maven packages. Please see [1] for very
valuable comments from Emmanuel Bourg.

Hope this helps,
