Well, first you need to fix those ambiguities - if you post your grammar then we can probably help. Then, there is either something screwy in your .g file that is causing ANTLR to bomb out, or your pom is not configured quite right in some way. So, again, post your grammar but also post the pom.xml and then we can help.
You should also change the encoding property in your pom.xml to be UTF-8 so you don't get warnings about using platform specific encodings.
