Bug Description

Consider following pom.xml snipplet. There are two annotation processors. Everything is fine if querydsl is last. However if querydsl is first the other processor (jpamodelgen) won't get executed. I'm not sure why. Perhaps they get chained and querydsl returns bad return code?

btw: there's no error in processing either of the processors

<plugin>
 <groupId>org.bsc.maven</groupId>
 <artifactId>maven-processor-plugin</artifactId>
 <version>2.0.2</version>
 <configuration>
  <processors>
   <processor>org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor</processor>
   <processor>com.mysema.query.apt.jpa.JPAAnnotationProcessor</processor>
  </processors>
 </configuration>
 <dependencies>
  <dependency>
   <groupId>org.hibernate</groupId>
   <artifactId>hibernate-jpamodelgen</artifactId>
   <version>${hibernate-jpamodelgen.version}</version>
   <scope>compile</scope>
  </dependency>
  <dependency>

   <artifactId>querydsl-apt</artifactId>

</plugin>

Which Querydsl version are you using? Could you provide the part of the Maven log where APT execution happens?

Here's an example. It's even simpler - using compiler plugin instead of additional processor plugin. Run:

mvn clean test

Test will fail. Reordering of annotation processor dependencies helps. Move hibernate-jpamodelgen before querydsl and it will work.

Fixed in SVN trunk.

The process method needs to return false so that other processors can reclaim the annotations.
