I would like to generate a class per package, when at least a class extending a certain base class is present in my package.

Currently I am doing this in a FirDeclarationGenerationExtension. When I see a class extending the base class of interest in getNestedClassifiersNames then I wrote that down and the next time that getTopLevelClassIds is invoked a return my new class id.

override fun getTopLevelClassIds(): Set<ClassId> {
        val packages =  mpNodeClassesEncountered.map { it.packageFqName() }.distinct()
        val topLevelValues = packages.map { ClassId(it, Name.identifier("Language${it.asString().replace(".", "_").capitalize()}")) }.toMutableSet()
        topLevelValues.removeAll(alreadyAddedClasses)
        topLevelValues.map { sli ->
            createTopLevelClass(sli, Key, classKind = ClassKind.OBJECT) {
                superType(StarLasuLanguage::class.classId.toConeType())
            }
        }
        alreadyAddedClasses.addAll(topLevelValues)
        return alreadyAddedClasses
    }

The problem is that reference to the object I generate are not resolved. The compiler behave as if the object does not exist.

Any idea about what I am doing wrong?
