Erreur in Installation PUGXMultiUserBundle - symfony

Question

I want to install PUGXMultiUserBundle. I followed the documentation of PUGXMultiUserBundle:https://github.com/PUGX/PUGXMultiUserBundle/blob/master/Resources/doc/index.md
I have downloaded the PUGXMultiUserBundle with success and I continued Creating my Entities. I created an entity User:
<?php
namespace Register\UserBundle\Entity;
use FOS\UserBundle\Model\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity
* #ORM\Table(name="user")
* #ORM\InheritanceType("JOINED")
* #ORM\DiscriminatorColumn(name="type", type="string")
* #ORM\DiscriminatorMap({"societe" = "Societe", "chercheur" = "Chercheur"})
*
*/
abstract class User extends BaseUser
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var string $image
* #ORM\Column(name="image", type="string", length=255)
*/
protected $image;
public $file;
protected function getUploadDir()
{
return 'image';
}
protected function getUploadRootDir()
{
return __DIR__.'/../../../../web/'.$this->getUploadDir()."/".$this->getId()."/";
}
public function getWebPath()
{
return null === $this->image ? null : $this->getUploadDir().$this->getId()."/".'/'.$this->image;
}
public function getAbsolutePath()
{
return null === $this->image ? null : $this->getUploadRootDir().$this->getId()."/".'/'.$this->image;
}
public function getAbsolutePath1()
{
return null === $this->image ? null : $this->getUploadRootDir().$this->image;
}
/**
* #ORM\PrePersist
* #ORM\PreUpdate
*/
public function preUpload()
{
if (null !== $this->file) {
// do whatever you want to generate a unique name
$this->image = uniqid().'.'.$this->file->guessExtension();
}
}
/**
* #ORM\PostPersist
* #ORM\PostUpdate
*/
public function upload()
{
if (null === $this->file) {
return;
}
// if there is an error when moving the file, an exception will
// be automatically thrown by move(). This will properly prevent
// the entity from being persisted to the database on error
$this->file->move($this->getUploadRootDir(), $this->image);
unset($this->file);
}
/**
* #ORM\PreRemove()
*/
public function storeFilenameForRemove()
{
$this->filenameForRemove = $this->getAbsolutePath1();
}
/**
* #ORM\PostRemove()
*/
public function removeUpload()
{
if ($this->filenameForRemove) {
unlink($this->filenameForRemove);
}
}
}
and the other Entity: societe:
<?php
namespace Register\UserBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use PUGX\MultiUserBundle\Validator\Constraints\UniqueEntity;
/**
* #ORM\Entity
* #ORM\Table(name="societe")
* #UniqueEntity(fields = "username", targetClass = "Register\UserBundle\Entity\User", message="fos_user.username.already_used")
* #UniqueEntity(fields = "email", targetClass = "Register\UserBundle\Entity\User", message="fos_user.email.already_used")
*/
class Societe extends User
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #var string $adressemail
*/
protected $adressemail;
/**
* #var string $namesociete
*/
protected $namesociete;
}
an finally the last Entity chercheur:
<?php
namespace Register\UserBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use PUGX\MultiUserBundle\Validator\Constraints\UniqueEntity;
use Symfony\Component\Validator\Constraints as Assert;
/**
* #ORM\Entity
* #ORM\HasLifecycleCallbacks
* #ORM\Table(name="chercheur")
* #UniqueEntity(fields = "username", targetClass = "Register\UserBundle\Entity\User", message="fos_user.username.already_used")
* #UniqueEntity(fields = "email", targetClass = "Register\UserBundle\Entity\User", message="fos_user.email.already_used")
*/
class Chercheur extends User
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #Assert\NotBlank
* #var string
*/
protected $region;
/**
* #Assert\NotBlank
* #var string
*/
protected $firstname;
}
The problem is when I want to generate my entities after : php app/console doctrine:generate:entities Register, a error message appeared in console:
[Doctrine\ORM\Mapping\MappingException]
Class "Register" is not a valid entity or mapped super class.
doctrine:generate:entities [--path="..."] [--no-backup] name
.
Can someone help me to fix this problem and Thank you.
