Help needed with Groovy + Maven + JUnit 4

Hi all,

I'm having trouble getting JUnit 4 test cases written in Groovy to work in Maven. With the attached POM file and Groovy test case file (which I put in "src/test/groovy/GroovyTestTest.groovy"), I get the Maven output shown below. I have attached the test report; it involves a "java.lang.IllegalAccessError: tried to access field org.codehaus.groovy.reflection.CachedClass.EMPTY".

This is with Maven 2.1.0 on Java 5 on MacOS.

Can anyone help?

Thanks!

Cheers,
  Alexander.
