Praise be to Ivy, which lets me do what I need without tremendous amounts of

hair-pulling and ball-ache. We now have Maven call out to an Ivy-based Ant task
to do the Proguard build (with Ivy maintaining a parallel copy of the
dependencies, unfortunately). It's a twisty maze of passages, but it gets the
Proguard build done during the right Maven phase so that all of its magical
building, version number changing, SVN commits, etc. can happen as usual during
the publishing process.
