Looking at javapackages-tools.spec I see several subpackages being created:
javapackages-tools, maven-local, gradle-local, ivy-local, python-javapackages

Looking at javapackages-tools there are several files that might be better
added to one of the others, like the maven-* files/directories.

But my main problem is the dependency of javapackages-tools to a lot of
python-packages, especially  python-pyxb.

I wonder if we can get rid of some of the pyton dependencies, to make
installation of javapackages on a minimal system possible.
