[antlr-interest] Maven problems with ANTLR 3.2

It should not be even referencing the SCM to be honest as the perforce plug-in is not useable in its present state. 

I am using 2.2.1 myself on Linux and Windows and having no such issue. It must be something to do with the Mac or your installation (are you going to the net for your repository or using a local cache?), but as my Mac is touring India at the moment, I cannot check the Mac version. Perhaps someone else can try this?
