Error with Mockito: "Could not initialize plugin: interface org.mockito.plugins.MockMaker"

[matteo-coni]

I can't to combine use of mockito and badua in testing of Apache projects. In particular the error is: "Could not initialize plugin: interface org.mockito.plugins.MockMaker (alternate: null)" when the test try to build the mock of any class. I have include any necessary library , indeed test work fine without badua and also with JaCoCo or other tool of coverage.

Hi @matteo-coni,

In theory, BA-DUA should work fine with Mockito.

Question: Are you using BA-DUA and JaCoCo activated at the same time? This may cause problems!

Do you have a reproducer for this bug that you can share with me ? With a reproducer will be much easier to understand what is going on.
