Hey folks,
we successfully published our first kotlin multiplatform library targeting android &amp; iOS to sign aws requests.

While integrating it in one of our production android apps I stumbled over a `java.lang.ClassNotFoundException` while running a JUnit test for the class that collaborates with our library.

This is just a problem while running JUnit tests, using the library while running the app works fine :thinking_face:

Any idea?

`kotlinx/serialization/SerializationKt` is an extension method from `kotlinx/serialization` we’re using internally in the library.

the dependency to our library in the android project  is declared as `implementation 'com.novoda:aws-v4-signer:0.0.1'`

Ok, I just realised this just happens when running the test from Android Studio, running it from the cli works fine.

Probably a bug with using `implementation`, which I wouldn't recommend using over `api` (which used to be `compile`) until you expect other developers may consume your library.

yep, it’s a known one: <https://youtrack.jetbrains.com/issue/KT-29343>
