Hey In my library (that will be distributed) I have simple Kotlin data class where some of the properties are nullable

// Kotlin class
data class Test(
val name: String,
val lastName :String?
)

// Generated Java class src
public final data class Test public constructor(name: kotlin.String, lastName: kotlin.String) { 
}

Since this class will be also used from Java is there any way to include Nullable and NonNull annotations in generated the code for the properties? Something like this:

// Generated Java class src
public final data class Test public constructor(@NonNull name: kotlin.String, @Nullable lastName: kotlin.String) { 
}

(I mostly care about NonNull):

The main drive for this behaviours is that now I can create new instance of Test class from Java and pass null values new Test(null, null) without any indication that this is wrong/undesired usage- I believe with annotations IDE would display error/waring 🤔

When I use IntelliJ to view the bytecode, and decompile it, the @NotNull and @Nullable annotations are there.

The decompiled to java class looks like this:

You are right @robstoll annotations are there - I think I found a bug in Kotlin Plugin or decompiler - I am investigating

You probably meant @Rob Elliot 😉
