JavaPoet + Android Studio "addModifiers(Modifier) cannot be applied to Modifier"

Question

I've built an annotation processor for my Android project that builds a source file using JavaPoet. However, every time I need to call addModifiers on any JavaPoet object, Android Studio flags it as an error. It will say either

Cannot resolve method addModifiers(javax.lang.model.element.Modifier)

or

addModifiers(javax.lang.model.element.Modifier) cannot be applied to javax.lang.model.element.Modifier

depending on which object I'm calling the method on. I've checked many times that the two fully qualified class names match perfectly. These methods in JavaPoet use VarArgs arguments, but that shouldn't make a difference since I'm compiling to Java 7.

Now here's the kicker: The package compiles just fine, and creates my source file. It only gives me the error in the IDE, not when javac runs. The modifiers are correct in the generated file.

So I guess what I want answered is: How do I get rid of the IDE error, and who do I report this to? Is this a JavaPoet issue, an Android Studio issue, or an IntelliJ issue, or something I haven't considered yet?

This does work because the checkerframework contains all of the javax.lang.model directly in the jar. Note this could potentially cause problems with inconsistent versions, so use with care. – Pyorrhea
