Support for @Generated annotation

Hi guys,

I just discovered the promising javax.annotation.Generated annotation [1]. I think this could be a very good solution to allow easy configuration of all quality tools (findbugs, cobertura, pmd, checkstyle, ...) that have to ignore generated code.

I understand this is not only Sonar but all these tools that have to be updated to support this annotation. BTW I think it could be great to track here the progress on this area.

The best would be that code generators themselves automatically add the @Generated(value=SOURCE) to the class/method/attribute with the correct value (ie modello, wsdl2java, ...). This way we could configure Sonar to ignore all code generated by a specific list of source code generators.

It seems that JPA 2 will use @Generated on the metamodel classes used for the new Criteria API (see JSR 317 spec).
