InYourProcessor.java

import javax.annotation.processing.SupportedOptions;

@SupportedOptions("debug") // declare the `debug` option
public final class InYourProcessor extends AbstractProcessor {

    /**
     * This is now your logging routine.
     */
    private void log(String msg) {
        if (processingEnv.getOptions().containsKey("debug")) {
            processingEnv.getMessager().printMessage(Kind.NOTE, msg);
        }
    }

}

Do you know if there is a way to activate the profile when you add -X (or --debug) option in command line?
