hello?

The issue is still there with KGP 2.1.20-RC-105 and KSP 2.1.20-Beta2-1.0.29

https://android-build.corp.google.com/test_investigate/invocation/I01400010365273224/test/TR39129624418138182/?blocking=blocking&status=none

RC will releases soon, do you have suggested fixes or can I disable these tests in the meantime?

Can you please apply the following patch: https://paste.googleplex.com/5920359738769408

Both failures are related to KAPT (low priority) so working around them for now instead of disabling the tests and losing KSP coverage.

It seems like only XAnnotationTest.typeReference_kotlin is a regression and that XTypeTest.missingTypes_names is just a change in log message.

Given that RC is coming soon, do you have some hints on what we should put in the bug for KAPT?

If you are filling a bug about the KAPT, then the following will help them:

Given the following source files:

// src/kotlin/Subject.kt
@MyAnnotation(singleType = Long::class)
class Subject {
}

// src/kotlin/MyAnnotation.java
public @interface MyAnnotation {
    Class<?> singleType();
}

in Kotlin KSP 2.1.20-Beta2 the KAPT stub is:

@MyAnnotation(singleType = kotlin.Long.class)
@kotlin.Metadata(mv = {2, 1, 0}, k = 1, xi = 48, d1 = {"\u0000\f\n\u0002\u0018\u0002\n\u0002\u0010\u0000\n\u0002\b\u0003\b\u0007\u0018\u00002\u00020\u0001B\u0007\u00a2\u0006\u0004\b\u0002\u0010\u0003\u00a8\u0006\u0004"}, d2 = {"LSubject;", "", "<init>", "()V", "kapt-2.1.20-issue"})
public final class Subject {
    
    public Subject() {
        super();
    }
}

where as in Kotlin 2.1.10 it is:

@MyAnnotation(singleType = long.class)
@kotlin.Metadata(mv = {1, 9, 0}, k = 1, xi = 48, d1 = {"\u0000\f\n\u0002\u0018\u0002\n\u0002\u0010\u0000\n\u0002\b\u0002\b\u0007\u0018\u00002\u00020\u0001B\u0005\u00a2\u0006\u0002\u0010\u0002\u00a8\u0006\u0003"}, d2 = {"LSubject;", "", "()V", "kapt-2.1.20-issue"})
public final class Subject {
    
    public Subject() {
        super();
    }
}

Notice the change in the value singleType, it is not being interop. Similarly if singleType = String::class is used, then the KAPT sub in 2.1.10 is @MyAnnotation(singleType = java.lang.String.class) where as in 2.1.20-Beta2 it is @MyAnnotation(singleType = kotlin.String.class) which is not right.

If you link the issue here I can also give them a sample project to repro.
