When trying to create Run configuration with a freshly installed SimpleTest plugin 0.2.5 I get this error message.
Plug-in net.sf.simpletest.eclipse was unable to load class net.sf.simpletest.eclipse.launcher.SimpletestTabGroup.
An error occurred while automatically activating bundle net.sf.simpletest.eclipse (394).
What version of eclipse are you running?
Could not repeat. Perhaps it was a temporary issue with my Eclipse configuration. I use PDT 2.1 SR1
