When building the project I end up with the following artifacts:
annotation-processor/src/test/java/org/hibernate/validator/ap/testmodel/FieldLevelValidationUsingBuiltInConstraints.class annotation-processor/src/test/java/org/hibernate/validator/ap/testmodel/ModelWithoutConstraints$SomeAnnotation.class annotation-processor/src/test/java/org/hibernate/validator/ap/testmodel/ModelWithoutConstraints.class
(not sure whether this is created by the IDE though)
