Scala Plugin internal error: no test class was found ??

i'm also experiencing this. any resolution?

I pesonally have switched to running my tests with the junit runner. Mainly because I like to ability to run and rerun (and debug) single tests via the test runner tree. I also like the ability to navigate directly to a (failed) tests from the test runner tree. Neither of these are (yet) supported when running via spec runner. This is a shame though, because the specs structure for tests is way way nicer and much more powerful than junit tests.

I do however still use the specs matchers, eg:

class ScheduleRulesSpec extends SpecsMatchers with ScalaCheckMatchers with Mockito {
  ...
  @Test def some_test {
      ...
      foo must containMatchOnlyOnce (bar)
    }
}
