Console cache: clear - Cannot declare a class already in use

Question

I have a problem with symfony 5.1 and the cache:clear command line.

All of my work is working great on the browser. I've make some refactoring and move some pictures and I had a problem (it was due to a bad way), but before know this I went to clear the cache to verify.

This is what the terminal tells me:

$ sc cache:clear

 // Clearing the cache for the dev environment with debug true

I don't know what can I show you for better understanding.

You have maybe to know I'm using the EasyAdminBundle 3.

This is my tree structure:

    ├─ .../

    ├─ Controller/
    |     ├─ Admin/
    |     |     ├─ Crud/

    └─ Kernel.php

In the src/Controller/Admin/Crud/UserCrudController.php file, I have that:

<?php

namespace App\Controller\Admin\Crud;

use App\Entity\User;
use ...

class UserCrudController extends AbstractCrudController
