Annotation processing exception: "Failed to analyze: java.lang.reflect.InvocationTargetException"

I’m writing my own annotation processor and I want to be able to annotate the return type of a function.

Here’s the code for the annotation:

@Retention(AnnotationRetention.SOURCE)
@Target(AnnotationTarget.FUNCTION)
annotation class ReturnType(val type: KClass<*>)

And part of the code from the annotation processor:

annotatedElement.enclosedElements
    .filter { it.kind == ElementKind.METHOD }
    .forEach { method ->
        val returnType = method.getAnnotation(ReturnType::class.java).type
    }

When I try to compile the code I get the following exception:

Does this help https://stackoverflow.com/a/7688029/992380?

It does! Catching the MirroredTypeException and extracting the typeMirror from it did the trick.
Thanks
