Hi - you should avoid setting up your own structure under source and use
the pre-known locations of the .g files. Read the docs at
www.antlr.org/antlr3-maven-plugin. The .g files should go under the
antlr directory and they should be in sub directories of this directory
that reflect the package structure you want for the generated files.
Include and lib, as well as import is then calculated automatically.
Also note that we are at ANTLR 3.2 and plugin 3.2 now, though I think
that Maven central is not syncing our repository right now and I have no
time to try and work out why.
