I'm trying to debug why Moshi doesn't work with Kotlin + ProGuard. The issue I'm seeing is that when ProGuard is enabled the call rawType.kotlin.primaryConstructor returns null. What sorts of things do I need to keep in order for kotlin-reflect to be able to find the primary constructor of a class at runtime? Just keeping the @Metadata annotation methods (as the library suggests) is not enough. Keeping all kotlin classes (-keep class kotlin.** { *; }) does work, but I'd rather just keep what I need.

Try keeping only the entry point to kotlin-reflect and its dependencies: -keep class kotlin.reflect.jvm.internal.ReflectionFactoryImpl { *; }

Didn't work 😞. I also just tried -keep class kotlin.reflect.** { *; } and that didn't fix it either, apparently I need to keep something outside of kotlin-reflect 🤔

aha - it was that class + keeping the whole Metadata annotation (the readme just says to keep the methods of that annotation)

thank you @udalov
