[antlr-interest] Error building from source: The scm url cannot be null

[Rick Mann]

Hi all,

I just downloaded antlr-3.2, and installed Maven 2.2.1. After downloading a bunch of jars, it ran into an error. The maven invocation and error are below. Did I do something wrong?

$ mvn -Dmaven.test.skip=true
