java.lang.NoSuchMethodError: okhttp3.internal.Internal.initializeInstanceForTests in Android Studio 4.1

Question

I just upgraded Android Studio 4.1 and got all the tests related to mock webserver failed in IDE but not in terminal. It passed fine before I upgraded to 4.1.

My Okhttp and mockwebserver version is 4.7.2

TestCase.kt

class RepositoryTest : BaseUnitTest() {
    private lateinit var mockWebServer: MockWebServer

    @BeforeEach
    override fun setUp() {
        mockWebServer = MockWebServer()
        mockWebServer.start()
        super.setUp()
    }

    @AfterEach
    override fun tearDown() {
        super.tearDown()
        mockWebServer.shutdown()
    }

    @Test
    fun scenario1() {
        ...
    }
}

Stack traces from IDE

java.lang.NoSuchMethodError: okhttp3.internal.Internal.initializeInstanceForTests()V

Answer 1

See https://github.com/square/okhttp/issues/5759

Likely you are mixing dependency versions. Check Intellij project view to ensure you are using a single version across all okhttp libraries

Answer 2

It happened to me and, like Yuri Schimke answered, I had two OkHttp versions in my project (one was brought by retrofit). I had to downgrade my OkHttp (less painful) to match the retrofit's Okhttp. Exclusion strategy also didn't worked well for me.
