kotlinlang

Hello
I have extracted Kotlin class from `jar` file (from Android library `aar`), decompiled it and I see that this Kotlin class is missing Kotlin metadata (class is not annotated with `@Metadata` annotation). What could be the reason?

The issue is that library user cannot use Kotlin related constructs like named arguments, so I wonder is there a setting or compiler flag to always add Kotlin metadata? :thinking_face:

expected result in compiled class:
```@Metadata(mv = {1, 6, 0}, k = 1, xi = 48, d1 = {"\000$\n\002\030\00"}..."})
public final class MyClass {
   ...
}```

Got the answer It is R8 bug <https://stackoverflow.com/questions/70315232/data-class-metada-is-removed-with-proguard-r8|android - Data class metada is removed with proguard / R8 - Stack Overflow>
