More than one file was found with OS independent path 'mockito-extensions/org.mockito.plugins.MockMaker'

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

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.

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.
