No tables are created
<p>Using Symfony I've created some Entity-classes like this one below:</p>

<p>But when I run</p>

<pre><code>php bin/console doctrine:schema:create
</code></pre>

<p>I only get the result:</p>

<p><em>No Metadata Classes to process.</em></p>

<p>So I wonder what am I doing wrong?</p>

<pre><code>namespace AppBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="dimension")
 */

class Dimension
{
    /**
     * @ORM\Column(type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @ORM\Column(type="integer")
     */
    private $width;

    /**
     * @ORM\Column(type="integer")
     */
    private $height;

//getters and setters are also created but removed from this code example

}
</code></pre>
