NoClassDefFoundError: org/hamcrest/Matchers using PowerMock-OSGi

[Christian Schwarz]

I get an NoClassDefFoundError for org.hamcrest.Matchers, when i run my Test as OSGi PlugIn test, but when i run it as plain JUnit test everthing works as expected. 

I am using the OSGi version of PowerMock and have all neccessary dependencies in my launch config. All Tests of my suite that dont use PowerMock have no

 problem to load the hamcrest class.It seems like the Testrunner doesnt see the class, for some reason.

What i am doing wrong? 

I also aksed this at Stackoverflow -> NoClassDefFoundError: org/hamcrest/Matchers using PowerMock-OSGi

It seems to be a problem with the bundle org.hamcrest.library. I filed an issue at powermock-osgi, see: https://code.google.com/p/powermock-osgi/issues/detail?id=2
