[news.eclipse.tools.jdt] How to make work this very simple example

[richard.fagot@xxxxxxxxx (Richard Fagot)]

Hi all,

I've just discover JDT-APT and I've tried to make my first annotation 
which always print error message. Unfortunatelly it does not work. Can you 
help me make it worked (I generate a simple jar with these three classes)

### Annotation ###
public @interface NoDuplicatedReturnType
{
}

### Processor  ###
public class NoDuplicatedReturnTypeProcessor implements AnnotationProcessor
{

	public NoDuplicatedReturnTypeProcessor(AnnotationProcessorEnvironment env)
	{
		_env = env;
	}

	public void process()
	{
		Messager messager = _env.getMessager();
		messager.printError("houhou");

	}

	public AnnotationProcessorEnvironment getEnvironment()
	{
		return _env;
	}

	AnnotationProcessorEnvironment	_env;

}

### Factory ###
public class NoDuplicatedReturnTypeProcessorFactory implements
AnnotationProcessorFactory 
{

	public Collection<String> supportedOptions() {
		return Collections.emptyList();
	}

	public Collection<String> supportedAnnotationTypes() {
		return annotations;
	}

	public AnnotationProcessor getProcessorFor(
			Set<AnnotationTypeDeclaration> atds,
			AnnotationProcessorEnvironment env) 
	{
		return new NoDuplicatedReturnTypeProcessor( env );
	}
	
	private static ArrayList<String> annotations = new ArrayList<String>();
	
	{
		annotations.add( NoDuplicatedReturnType.class.getName() );
	}
}
