Symfony: User roles with doctrine: no entities or tables created - symfony

Question

I followed the instructions given in the Symfony-Book to get a user-role relation with doctrine updating them in my database.
Symfony - User/Role - Doctrine
But when I update my entities via doctrine:generate:entities, it only generates the existing User.php, but doesn't touch the Role.php. This wouldn't bother me, if the tables in my databse would update with doctrine:schema:update --force. But they don't. The mentioned tables aren't created. In fact, nothing happens. Can you please help me? I am looking forward to any good solution.
My User.php
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\AdvancedUserInterface;
use Doctrine\Common\Collections\ArrayCollection;
/**

*
* #ORM\Table(name="user")

First tip: give your user table a different name, eg #ORM\Table(name="acme_user").
Second: add in your user class:
/**
* User's roles.
*
* #var ArrayCollection
*
* #ORM\ManyToMany(targetEntity="Role", inversedBy="users")
*/
private $roles;
and in your role class
/**
* #ORM\ManyToMany(targetEntity="User", mappedBy="roles")
*/
private $users;
