Question

I am getting this error when running a tester plugin (using SWTBot), for my product: 

!ENTRY org.eclipse.ui 4 4 2013-11-07 18:16:48.608
!MESSAGE Referenced part does not exist yet: org.eclipse.jdt.ui.PackageExplorer.
2013-11-07 18:16:48,611 main ERROR

Additionally, i get this exception that basically says that i haven't set my tester plugin as a dependency of my product:

Exception in thread "WorkbenchTestable" java.lang.IllegalArgumentException: No Classloader found for plug-in com.project.test.swtbot

I am using Eclipse RCP. Am i interpreting the error correctly? Does anyone have a clue of how to solve this issue?

Many thanks in advance

Was it helpful?

Solution 2

Figured it out. For anyone haveing this issue, you should always use (unless somethign creepy happens) "all workspace and enabled target plug-ins" in the launch configurations. This enables your test to validate every dependency that you might not be considering.

Cheers
