doctrine2 autloader with cli must use AnnotationRegistry

Question

I must use \\Doctrine\\Common\\Annotations\\AnnotationRegistry::registerFile to access the annotation registry in entity files.

This part is required to use

Answer 1

It seems your AnnotationRegistry isn't set up.

Add the following to your script:

use Doctrine\Common\Annotations\AnnotationRegistry;  

AnnotationRegistry::registerFile("/path/to/doctrine/lib/Doctrine/ORM/Mapping/Driver/DoctrineAnnotations.php");

see Doctrine manual on Annotations for the detailed explanation.
In short: to read the annotations PSR-0 and spl autoloading can't do the job, you have to use their solution.
