在Kotlin中覆盖Java @Nullable varargs方法时，IDE抱怨它没有覆盖任何内容

Question

I've got a Java method interface that looks something like this:

@NonNull Future<List<Item>> search(@NonNull String query, @Nullable EntityType... types);

and when I implement it in Kotlin like this (via IntelliJ implementation generation):

override fun search(query: String, vararg roomType: EntityType?): Future<List<Item>>

the IDE complains that it "overrides nothing". However, if the @Nullable annotation didn't exist in the Java class, there are no lint errors.

Answer 1

The annotation is labeling the array of varargs as nullable, not the values within the array. This seems to work:

override fun search(query: String, roomType: Array<EntityType>?): Future<List<Item>>
