Android Room generates DAO with error when method returns RxJava Completable

I have @Insert method in Dao interface like this:

@Insert(onConflict = REPLACE)
fun insertOrUpdateAllMessages(vararg messages: QuestMessageDbModel): Completable

When I build my project I get error:

error: local variable questsModels is accessed from within inner class; needs to be declared final
      __insertionAdapterOfQuestDbModel.insert(questsModels);
                                              ^

When I open generated QuestDao_Impl.java, I see there such code: enter image description here

What am I doing wrong? I tried to replace vararg argument with List, but got same error.

As said in this stackoverflow question, enabling java8 compatibility fixes the problem.

Add this to your desired project module gradle file, inside the android closure:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}
