No changed detected when run migrations


#1

I added a new entity
<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Sylius\Component\Resource\Model\ResourceInterface;

/**
 * @ORM\Entity(repositoryClass="App\Repository\ManufacturerRepository")
 * @ORM\Table(name="sylius_manufacturer")
 */
class Manufacturer implements ResourceInterface
{
/**
 * @ORM\Id()
 * @ORM\GeneratedValue()
 * @ORM\Column(type="integer")
 */
private $id;

/**
 * @ORM\Column(type="string", length=255, nullable=false)
 */
private $name;

but when I run php bin/console doctrine:migrations:diff I get No changes detected in your mapping information.
What I’m doing wrong?
Thank you
