java - Performing a final action after annotation processing -

-

so have annotation that, although can declared multiple times, needs access same properties file. using static registry in annotation processor track if file has been created, , store writer file. far works fine, problem figuring out when save file. making call roundenv.processingfinished (or whatever method is) @ end of annotation processor, , if returns true save file. problem having that, if source fines generated, , compiler goes new round of processing not contain of annotation, file not ne saved. thinking adding entirely new processing supports every annotation, claims none, , making check there. feel clunky option, since spec indicates processor should support annotations process. there better way of doing this, or should go additional processor model?
