Hey folks,
we successfully published our first kotlin multiplatform library targeting android & 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 🤔

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'

[Tobi]

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
