Zend Framework 2 + Doctrine 2 Custom configuration with YML mapping not working

Question

I am trying a different configuration to working with a new Project.

What I want to do is to create a database by writing sql on hand.
After it I want to do a convert-mapping from database to "YML" instead of php annotations. So, to finish it, I want to convert those YML mapping information to Doctrine Entity, inside a ZF2 Module.

I am Using in composer:

"doctrine/doctrine-orm-module" : "0.7.0",
"doctrine/doctrine-module" : "0.7.*",

In global.php configuration

'doctrine' => array(
     'connection' => array(
         // default connection name
         'orm_default' => array(
             'driverClass' => 'Doctrine\DBAL\Driver\PDOMySql\Driver',
             'params' => array(
                 'host'     => 'localhost',
                 'port'     => '3306',
                 'user'     => 'root',
                 'password' => '****',
                 'dbname'   => 'gear',
                 'charset'  => 'utf8'
             ),
         )
     )
 ),

On the Target Module

'doctrine' => array(
    'driver' => array(
        /* This is where you can change the Mapping Driver */
        'orm_default' => array(
            'drivers' => array(
                 'Application\Entity' => 'application_entities_yaml'
             ),
        ),
       'application_entities_yaml' => array(
            'class' => 'Doctrine\ORM\Mapping\Driver\YamlDriver',
            'paths' => array(__DIR__ . '/../src/' .__NAMESPACE__.  '/Yml')
        ),
    ),
),

I am looking to use a custom place to put the YML annotations, on a ZF2 Action I use a exec thats generate this command:

vendor/doctrine/doctrine-module/bin/doctrine-module orm:convert-mapping --namespace="Gear\\Entity\\" --force --from-database yml module/Gear/src/Gear/Yml

Who saves correcty the YML mapping data into the folder module/Gear/src/Gear/Yml It is exactly the path that I put into "application_entities_yaml" in the module config file.

But when i try to finally create the Entitys to get the work done, with this command:

vendor/doctrine/doctrine-module/bin/doctrine-module orm:generate-entities module/Gear/src/

or with

vendor/doctrine/doctrine-module/bin/doctrine-module orm:generate-entities --generate-annotations=1 module/Gear/src/

I got just:

'No Metadata Classes to process.' 

I need to discovery how make Doctrine recognize where i put the metadata classes, to avoid this errors and go on with the project. I'll work with YML entities cuz is the best way to I teach non 'php' programmers write entities by the way. So is important to work with YML.

How to make Doctrine recognize those mapping and convert to entity without problems?

On the Target Module

Just change the Application\Entity to Module\Entity aka Gear\Entity and it works!

'doctrine' => array(
    'driver' => array(
        /* This is where you can change the Mapping Driver */
        'orm_default' => array(
            'drivers' => array(
                 'Gear\Entity' => 'application_entities_yaml'
             ),
        ),
       'application_entities_yaml' => array(
            'class' => 'Doctrine\ORM\Mapping\Driver\YamlDriver',
            'paths' => array(__DIR__ . '/../src/' .__NAMESPACE__.  '/Yml')
        ),
    ),
),
