The <info>doctrine:generate:entities</info> command generates entity classes
and method stubs from your mapping information:

You have to limit generation of entities:

* To a bundle:

  <info>./app/console doctrine:generate:entities MyCustomBundle</info>

* To a single entity:

  <info>./app/console doctrine:generate:entities MyCustomBundle:User</info>
  <info>./app/console doctrine:generate:entities MyCustomBundle/Entity/User</info>

* To a namespace

  <info>./app/console doctrine:generate:entities MyCustomBundle/Entity</info>

If the entities are not stored in a bundle, and if the classes do not exist,
the command has no way to guess where they should be generated. In this case,
you must provide the <comment>--path</comment> option:

  <info>./app/console doctrine:generate:entities Blog/Entity --path=src/</info>

You should provide the <comment>--no-backup</comment> option if you don't mind to back up files
before to generate entities:

  <info>./app/console doctrine:generate:entities Blog/Entity --no-backup</info>
