After adding this to my Android project, normal JUnit tests fail

Using version 1.4.0.

I get this error:

java.lang.AbstractMethodError: org.powermock.api.mockito.internal.mockmaker.PowerMockMaker.isTypeMockable(Ljava/lang/Class;)Lorg/mockito/plugins/MockMaker$TypeMockability;

This test passed prior to adding mockito-kotlin. It complains on this line:

Thing thing = Mockito.mock(Thing.class); // Thing is a public INTERFACE defined in Java

If I remove that, the test still fails, but at a different line. I think it’s here:

@Mock Thing2 thing2; // Thing2 is a public non-final CLASS defined in Java

Other dependencies in build.gradle:

    testCompile 'junit:junit:4.12'
    testCompile 'org.hamcrest:hamcrest-library:1.3'
    testCompile 'org.mockito:mockito-core:2.0.5-beta'
    testCompile("org.powermock:powermock-api-mockito:$powermock_version") { // 1.6.2
        exclude module: 'hamcrest-core'
        exclude module: 'objenesis'
    }
    testCompile("org.powermock:powermock-module-junit4:$powermock_version") {
        exclude module: 'hamcrest-core'
        exclude module: 'objenesis'
    }

@starkej2 thanks for asking; I had meant to return and discuss my findings. Basically, I just removed PowerMock from the project. It has a strict dependency on a beta version of Mockito2, and it did not seem as if it would be updating that in the near future. Fortunately, after some refactorings it was no longer necessary for us to use PowerMock – normal Mockito was fine.

A caveat: if/when you update Mockito to the latest, and assuming you also use Hamcrest, you’ll find a few breaking changes from the Mockito beta. They’re relatively easy to fix, however.

I appear to be caught in dependency hell. Our project also uses PowerMock, which has a hardcoded dependency on an old version of Mockito. From my investigation so far, this won’t really be fixed until PowerMock 2 is released, and no clue when that will be.

I’ll hack away at it a bit more (with an axe), and update this issue if I find a solution. Thanks for the hint about Mockito 2.7.21.
