[rules-users] problem in Maven tests: class antlr CharStream not found, although it is there!

You need antlr-runtime jar in your classpath, although maven should get
it as a transitive dependency.
Try running:
mvn help:effective-pom
That will show you what maven is using as pom after resolving
dependencies. If antlr-runtime jar is not there or if you have the wrong
version, that would be the problem.
