[ http://jira.codehaus.org/browse/MANTLR-7?page=all ]
Dennis Lundberg closed MANTLR-7.
--------------------------------
Resolution: Won't Fix
That is because you are trying to use a Maven 1 plugin in Maven 2. You need to
change a couple of lines in your pom to use the Maven 2 version:
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-antlr-plugin</artifactId>
<version>2.0-beta-1</version>
> Cannot execute the plugin automatically in a pom
