[antlr-interest] Maven problems with ANTLR 3.2

[William B. Clodius]

I am trying to build ANTLR 3.2 with maven 2.2.1 on Mac OS X 10.6.2 and am having problems with what I believe is a null pointer exception. The test below is the result of trying to rerun maven after my first build. Any suggestions?

bash-3.2$ mvn -Dmaven.test.skip=true | more
