Their is a mirror at github: http://github.com/antlr
incidentally, the error is fixed in the the development branch.
I don't know why the wiki download doesn't suggest downloading from
github or perforce instead of offering an outdated source archive with
a faulty pom.xml.

cloning the repo fails with:
Cannot obtain needed tree 23d67ec01a2eba755068ead240ab22f8b2582344
also, there are no tags setup...

but you can download the master HEAD using the github web interface,
unzip, and:

mvn -N install
mvn -Dmaven.test.skip=true
mvn -Dmaven.test.skip=true package assembly:assembly
