mockito-android fails with AndroidStudio 4

See original GitHub issue

Env

Using:

mockito 3.3.3:
- androidTestImplementation "org.mockito:mockito-android:$mockito"
- testImplementation "org.mockito:mockito-core:$mockito"
Android Studio 4.0
kotlin 1.3.72.

Description

Having androidTestImplementation "org.mockito:mockito-android:$mockito" in gradle causes the unit test (which is not what androidTestImplementation is intended for) to fail when I call mock function I get an error on MockMaker:

I need to mock objects in my Instrumentation Tests also, so I need this dependency.

What can I do?
