the name of class is already in use

Question

I have a problem with symfony:

Fatal error: Cannot declare class App\Entity\UserGroup, because the name is already in use in /var/www/app/src/Entity/UserGroup.php on line 17).

I emptied the cache and reinstalled the packages but the problem still remains.

The class:

<?php

namespace App\Entity;

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\Common\Collections\Collection;
use Doctrine\DBAL\Types\Types;
use Doctrine\ORM\Mapping as ORM;

/* @ORM\Table(name="UserGroup", indexes={@ORM\Index(name="usergroup_license_id_foreign", columns={"license_id"})})
 * @ORM\Entity
 * @ORM\Entity(repositoryClass="App\Repository\UsergroupRepository")
/
class UserGroup{
    / @var int
     * @ORM\Column(name="id", type="integer", nullable=false)
     * @ORM\Id * @ORM\GeneratedValue(strategy="IDENTITY")
     */ 
    private $id;

Welcome to Stack Overflow!

Assuming you're using PHPStorm for development, I'd suggest trying the following:

• Hit command-shift-o to bring up the class-opening dialogue box
• Type in UserGroup to see what classes already exist
• Depending on your needs, you can then either edit that existing class or create your new class using a different namespace -- something other than App\Entity

I hope that helps!
