This is a very important point, so let me spell it out even if it may be
obvious to you guys:
We have two very different use cases for Maven in Debian:
1. For users: Maven needs to function the same as upstream.
But maybe with restrictions I already explained in another mail;
2. For building Debian packages: This needs to use Debian versions of
It's important to remember which use case a particular feature is meant for.

How would this work? Having a build-dep will not install anything in the
Maven repository, as I guess Maven would expect, and certainly not binary
I think the idea of Trygve was symlinks or something. We can also have
a script to add every debian-java package installed in a xml file so
that maven could know what is installed and where (and which version).
Another issue: Maven projects tend to specify exact version of their
dependencies. For building Debian packages, we need to get Maven to use
whatever version we have in Debian (and just make sure it's recent enough).
Also, we try to have less possible different versions (we try to have
the latest stable), but with Maven, you can work with older versions
of a lib. Do we accept this?
