Why doesn't NetBeans IDE see the generated sources?

Question

I have a Maven-built web-app that uses JPA 2.0 at the back end. The JPA provider is EclipseLink 2.3.2.

When I build the project (and it deploys runs successfully) it bu

After reading @jeqo answer, I tested if, by manually renaming:

 "${project.build.directory}/generated-sources/annotations" to ".../generated-sources/hibernate-jpamodelgen" 

would make a difference to Nebeans (I'm using v8.2 on ubuntu 16.04).

Everything worked like a charm.

I then modified the pom file as follows:

1) removed the "org.hibernate: hibernate.jpamodelgen" dependency.

2) configured the maven-compiler-plugin as follows:

   
    >org.apache.maven.plugins
    maven-compiler-plugin
    3.6.1
    
      -proc:none        
    
  

• These two steps is to make sure that the hibernate-jpamodelgen does not run on auto-pilot just by adding it in the project dependency list. Please refer to JPA Static MetaModel Generator doc.

3) added the following plugin with configuration

  
    org.bsc.maven
    maven-processor-plugin
    3.2.0
    
      
        process
        
          process
        
        generate-sources
        
          
            org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor
          
          ${project.build.directory}/generated-sources/hibernate-jpamodelgen/
        
      
    
    
      
        org.hibernate
        hibernate-jpamodelgen
        5.2.9.Final
      
    
  

This config is directly from the Hibernate JPA Static Metamodel Generator documentation page except for the following line:

${project.build.directory}/generated-sources/hibernate-jpamodelgen/

This line simply generates the metamodel in the directory named after the maven plugin name. From this point, I got all Netbeans references working at design time as if the generated classes were in the src directory subtree.

Hope this helps,
