Hi. What’s the best way to have functions / classes / etc visible across a Gradle project modules only? internal makes it visible only for the specific module. I see compiler supports -Xfriend-paths but that’s completely undocumented and as far as I know is not supported in Kotlin Gradle plugin

public makes it visible outside of the module; at that point you can control consumers of the module (they have to declare a dependency on it to use it).

@Chris Lee yes, but this is a library — I want to have some components visible to the “library group” of modules but hidden from general consumers

the best alternative at the moment is an @RequiresOptIn annotation https://kotlinlang.org/docs/opt-in-requirements.html

@Adam S that’s a bit disappointing, but I guess you’re right — that’s how KotlinX coroutines does with @InternalCoroutinesApi
