Hey, I wondered if there may be something like an annotation that can be added to a Java or Scala method to make it invisible for Kotlin but still visible for those languages.

in the end, it’s bytecode
while each language creates its own flavor
it would be very hard to tell from the bytecode from what language it’s generated

I actually found that

@kotlin.Deprecated(message = "", level = kotlin.DeprecationLevel.HIDDEN)
public void doSomething() {}

does seem to work! The function can still be called from Java but not from Kotlin.

pretty sneaky 👍

It doesn't seem to work from Scala however, which was my ultimate goal 😞

Try submitting an issue with the feature request. Seems pretty nice to have
