[antlr-interest] Maven problems with ANTLR 3.2

[Jim Idle]

I am not sure why this would be different on your Mac. It is possible though that I did not specify a specific version of the SCM plugin and so your build has picked some newly released version which does not like the fact that the SCM is seemingly null. However the only place where I specified the SCM was in the Java runtime pom, then I abandoned the scm idea because the perforce scm plugin is terrible and full of bugs. So, you could just remove the scm reference from that pom.xml file and see if it makes a difference. However, the scm isn't null in that reference so I don't know why you would get this and nobody else does.
