I've taken a first stab at implementing an XDoclet (version 1)
plugin for Maven 2.
As a sideeffect an AntRun plugin was also created - you can add
Ant script to the POM or call build.xml files.
It only works on non-released versions of m2 - details on the site.
So if you're using bleeding edge maven2 and you want to try out these
plugins, be my guest! But beware: documentation is thin and it's just
a preliminary version, to see if it's something the community wants.
So don't expect too much!
