Description

When I create the following simple groovy test case 

class ExampleTest extends GroovyTestCase {
  public void testSomething() {
    assert 3 + 2 == 4
  }
}

and I want to run it with Debug As -> JUnit Test in Eclipse I get the following error:

This only happens if I set the Groovy compiler to 1.6 - when I switch to 1.7 it works

I am having this problem with my Grails 1.2.1 application too which includes groovy 1.6.7

Did you do a full recompile after switching from 1.7 to 1.6? ValueRecorder being a 1.7 class won't be found on 1.6 - but it shouldn't be getting looked for if the compilation has been done by 1.6. Also, the groovy library dependency within the project is groovy-all-1.6 is it? and not still 1.7? We should probably be forcing a recompile on version switching.

I had to follow the instructions here

http://docs.codehaus.org/display/GROOVY/Compiler+Switching+within+Groovy-Eclipse

after removing groovy 1.7 from the bundles info file everything worked as expected

Note that I have not been able to reproduce this locally at all. And now it seems that the problem has resolved itself on the forum. Closing this as cannot reproduce, but please re-open if you still do have the problem.
