title: Updating database schema
body: <p>I try to run :</p>
  
  <pre><code>php bin/console doctrine:schema:update --force
  </code></pre>
  
  <p>but I have this exception:</p>
  
  <pre><code>Invalid mapping file 'App.Application.Sonata.UserBundle.Entity.Group.orm.xm
    l' for class 'App\Application\Sonata\UserBundle\Entity\Group'.
  </code></pre>
  
  <p>I extended SonataUserBundle on my App\Application folder. The entities are present on App\Application\Sonata\UserBundle\Entity.</p>
  
  <p>On my doctrine file, I mapped like that:</p>
  
  <pre><code>orm:
          auto_generate_proxy_classes: true
          naming_strategy: doctrine.orm.naming_strategy.underscore
          auto_mapping: true
          mappings:
              App:
                  is_bundle: false
                  type: annotation
                  dir: '%kernel.project_dir%/src/Entity'
                  prefix: 'App\Entity'
                  alias: App
              SonataUserBundle: ~
              FOSUserBundle: ~
              ApplicationSonataUserBundle: ~
  </code></pre>
  
  <p>But still can't update schema.</p>
