java.lang.NoClassDefFoundError: org/mockito/MockitoAnnotations$Mock #678
Description
PowerMock version 1.6.5 fails to initiate during a test due to a class that was removed in newer versions of Mockito 2.
I don't know the exact version when it started failing, but currently:
"org.powermock:powermock-api-mockito2:1.6.5"has a dependency on Mockito 2.0.42-Beta. All works fine.
However, if Mockito is explicitly updated to newer versions (e.g. 2.0.70-Beta at time of this issue submission), PowerMock fails during initialization with the following issue:

... 42 moreThe issue occurs in Line 117 of AnnotationEnabler.java:
@SuppressWarnings("unchecked")
@Override
public Class<? extends Annotation>[] getMockAnnotations() {
return new Class[]{org.mockito.Mock.class, Mock.class, org.powermock.core.classloader.annotations.Mock.class};
}The issue is that Mock.class is imported as: import org.mockito.MockitoAnnotations.Mock.
Unfortunately, in later versions of Mockito2, MockitoAnnotations does not include the Mock interface found in earlier versions as it was deprecated and has since been removed.
The easiest fix appears to be to just remove Mock.class from the array of Class[] annotations returned by the getMockAnnotations function.
In the meantime, we are staying with version 2.0.42-Beta that is brought in when including the powermock-api-mockito2 library.
