Hello everyone.  
I have created a simple starting pulgin. I am now stuck creating my mautic default database table.  
I have created my entity and my repository, on symfony I have a command to create the table, but on mautic how is it created? I tried updating the plugin but nothing just isn’t created. Suggestions?

I created an entity based on symfony knowledge but sending the command to create the table with columns gives me this error.

$ php bin/console doctrine:schema:update --dump-sql

In MappingException.php line 56:

No identifier/primary key specified for Entity “MauticPlugin\MauticDemoBundle\Entity\Demo” sub class of “Mautic\CoreBundle\Entity\CommonEntity”. Every Entity must have an identifier/primary key.

The key id is set like this →

class Demo extends CommonEntity

{

```
/** @Id @Column(type="integer") */

private $id;

/**

 * @var string

 * @ORM\Column(type='string' , lenght='255)
