Instrumented Tests Will Not Run -- 6 files found with path 'META-INF/LICENSE.md'

Question

Edit: Found out that MockK is causing this issue. I guess it is duplicating these files when I'm mocking my API request. When I remove MockK and/or Mockito. I do not get these errors. Any ideas?

Getting this error stating that there are these duplicate meta data files. I tried adding the packagingOptions block in my build.gradle file to exclude these files, but then my tests won't run at all. Is there a way to manually remove the duplicates? Where would these files be located? Any help is greatly appreciated. I am lost lol.

Tests:

    @RunWith(AndroidJUnit4::class)
    class ViewModelTests {
    
        @get:Rule(order = 1)
        val testRule = ActivityScenarioRule(MainActivity::class.java)
    
        private lateinit var viewModel: NewsViewModel
        private lateinit var repositoryImpl: RepositoryImpl
        private val context = InstrumentationRegistry.getInstrumentation().targetContext
    
        @Before
        fun setUp() {
            val newsDao = NewsDatabase.getDatabase(context).myDao()
            val newsApi = mockk<NewsApi>()
            viewModel = mockk()
            repositoryImpl = RepositoryImpl(newsApi, newsDao)
        }
    
        @Test
        fun test_empty_database() = runBlocking {
            assertEquals(0, repositoryImpl.getNewsFromDatabase.value?.size)
        }
    }

Answer 1

You can choose among the ResourcePackingOptions pickFirsts, merges, and excludes. Depending on the licenses, you might not be allowed to exclude them.

https://developer.android.com/reference/tools/gradle-api/8.0/com/android/build/api/dsl/ResourcesPackagingOptions

Android Studio projects default exclude licenses that don't require it (AL2 and LGPL2). For the rest, merging them together is a reasonable approach -

packagingOptions {
    resources {
        excludes += "/META-INF/{AL2.0,LGPL2.1}"
        merges += "META-INF/LICENSE.md"
        merges += "META-INF/LICENSE-notice.md"
    }
}
