Real method on mocked object is always called

I am trying to mock a class from a kotlin library with org.mockito:mockito-inline:2.7.19:

class TheTest {
    val kit: AndroidKit = mock()
    val resources: Resources = mock()

    @Test
    fun stepsIntoFunctionOfMockedClass() {
        given(kit.getResource(resources, 123, String::class)).willReturn("resource")
    }
}

When I do this first the test runs fine:

given(resources.getString(any())).willReturn("")

In the given statement the real function kit.getResource() is called which leads to an NPE since function calls on resources are not mocked. Any ideas?

Sample project to reproduce androidKit library

@craigmiller160 I had the same issue, the problem is the method is final, if you can set the method to open the issue will go away. Isn’t ideal but is a workaround that I used for a class. I think the solution will be that Mockito should complain about the final method/function instead of calling the real method.
