TypeReference.asTypeName() does not copy type annotations

[efemoney]

It seems type annotations are not copied into the TypeName constructed from a TypeReference

Can you please share a concrete example?

We have this top level function:

@ContributesJsonAdapter
internal fun Moshi.Builder.componentModelAdapter(
  types: @JvmSuppressWildcards Set<ComponentTypeMapping<*>>
) {
  add(ComponentModelAdapterFactory(types))
}

The issue here is that when you call ParameterReference.type().asTypeName() the resulting TypeName does not include the type annotations ie @JvmSuppressWildcards in the example above.

A fix/workaround is to manually copy the type annotations (for Psi, havent tried with Descriptor APIs)

internal fun KtAnnotated.annotationSpecs(module: ModuleDescriptor) =
  annotationEntries.map { it.toAnnotationReference(null, module).toAnnotationSpec() }
...

typeName = (it.type() as TypeReference.Psi).run {
  asTypeName()
    .copy(annotations = type.annotationSpecs(module)) // manually copy type annotations
},

I'd be happy to merge a PR. You could use https://github.com/square/anvil/blob/main/compiler/src/test/java/com/squareup/anvil/compiler/internal/reference/TypeReferenceTest.kt to write a test for this.
