Command "doctrine:generate:entities" is not defined - symfony

Question

I encounter a problem with Symfony and the Doctrine entities generator.
When I call php app/console doctrine:generate:entities MyCompany, command fail and throw this exception :
[InvalidArgumentException]
Command "doctrine:generate:entities" is not defined.
Did you mean one of these?
doctrine:generate:entity
doctrine:generate:form
doctrine:generate:crud
I saw in many post people who had similar problems. But theirs related the doctrine:generate:entity command. They had forgotten :
"sensio/generator-bundle": "2.3.*" // in composer.json
and
new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle(); // in AppKernel
In my case everything is OK with composer.json and AppKernel. For example, these commands work : doctrine:generate:entity, doctrine:generate:form and doctrine:generate:crud
But doctrine:generate:entities doesn't :/
Here is an extract from my php app/console list command :

Ok I found the solution to my problem so I post the answer here hopping that it might help somebody one day :)
The command doctrine:generate:entities is provided by the file DoctrineBundle/Command/GenerateEntitiesDoctrineCommand.php (https://github.com/doctrine/DoctrineBundle/blob/v1.2.0/Command/GenerateEntitiesDoctrineCommand.php). And this file was mysteriously disappeared ! It's weird...
To fix that I deleted doctrine/doctrine-bundle folder from vendors and run a composer update
Voilà :)
