AnnotationProcessor option not recorgnized by any processor

Question

I have written an annotation processor. The user can pass an option as parameter for the processor. I can also read this parameter in my annotation processor. So far so good, everything works like expected!

However, I get a warning from the compiler, that the option passed to the annotation processor has not been recorgnized by any annotation processor:

Warning:The following options were not recognized by any processor: '[fragmentArgsLib]'

Actually, my processor has recognized and read this option successfully:

@Override public boolean process(Set<? extends TypeElement> type, RoundEnvironment env) { String fragementArgsLib = processingEnv.getOptions().get("fragmentArgsLib"); ... }

I guess I have to say manually that I have used this option to make this compiler warning disappear. Does anyone of you know how to do that?

Might be just a typo in your post, but your code fragment declares a variable with name fragementArgsLib instead of fragmentArgsLib — user684934

yes, thats a typo, but that's just a variable name ... the getOptions.get("fragmentArgsLib") is correct and is matching '[fragmentArgsLib]' ... — sockeqwe

Found the answer, you have to specify which options are supported by your annotation processor by overriding getSupportedOptions() or using @SupportedOptions annotation (since java 7)
