Need help with annotation processor . I have created a simple annotation processor which uses @autoservice annotation that checks whether the field which is annotated is final. But it is not showing any compile time errors. This is my configuration
Annotation:
@Retention(RetentionPolicy.SOURCE) @Target(ElementType.FIELD) public @interface Store { int temp() default 0; } Annotation Processor:
@SupportedAnnotationTypes("com.self.Store") @AutoService(Processor.class) public class Process extends AbstractProcessor { @Override public boolean process(Set<? extends TypeElement> annotations, RoundEnvironment roundEnv) { for (Element element : roundEnv.getElementsAnnotatedWith(Store.class)) { TypeElement typeElement = (TypeElement) element; for (Element element2 : typeElement.getEnclosedElements()) { VariableElement variableElement = (VariableElement) element2; if (!variableElement.getModifiers().contains(Modifier.FINAL)) { processingEnv.getMessager().printMessage(Diagnostic.Kind.ERROR, "it should be final"); } } } return true; } } pom file:
