Question

More than one file was found with OS independent path 'mockito-extensions/org.mockito.plugins.MockMaker' getting this error while adding androidTestImplementation "org.mockito:mockito-inline:2.15.0"

in gradle to mock final class

Answer 1

If you are using Koin dependency injector, I found the solution on this Github issue.

Try androidTestImplementation ("org.koin:koin-test:$koin_version") { exclude group: 'org.mockito' }

It worked for me, I hope this may help others in the future.

Answer 2

In my case I resolved this issue by removing dexmaker dependency from the build.gradle

So, I removed the below dependency

androidTestImplementation "com.linkedin.dexmaker:dexmaker-mockito:2.12.1"

and kept only the below Mockito dependency

androidTestImplementation "org.mockito:mockito-android:2.25.0"

Not sure if that your case, but it solves mine.

Answer 3

The only correct answer is PowerMockito does not support the Davik VM Android uses, it is meant for a standard JVM. So you can't use it with instrumented tests, only unit tests. I have heard there's a library called OpenDex that allows you to use PowerMockito even with Android but it seems a bit involved to setup and I haven't personally tried it.

Answer 4

For Android, you usually just want

androidTestImplementation "org.mockito:mockito-android:<latest-version>"

You especially don't want mockito-inline because it configures the wrong MockMaker (mock-maker-inline) instead of AndroidByteBuddyMockMaker which is the only one working on Android that is distributed by the Mockito project. If you need advanced capabilities or faster mocking, head over to the dexmaker project.
