I created a doctrine annotation 

```
namespace Fondative\GenBundle\Front\Annotation;
use Doctrine\Common\Annotations\Annotation;

/**
* @Annotation
* @Target("PROPERTY")
*/
class ReferenceAnnotation extends Annotation {

}

use Fondative\GenBundle\Front\Annotation\ReferenceAnnotation ;

/**
 * A Driver.
 * 
 *
 * 
 * @ORM\Entity
 * 
 */
class Driver {
    /*
     * @Reference
     */
    private $name;

```

I get this exception 

> 
> [Semantical Error] The annotation "@Reference" in property
>  Fondative\TestBundle\Entity\Driver::$name was never imported.
