Symfony2无法从doctrine-bundle运行命令行任务

Question

我正在试图找出为什么我无法从Symfony2（2.2）的主教条 - 包中看到（并且当然运行）命令行任务。当我执行

php app/console

我只看到：

doctrine

  doctrine:database:drop              Drops the configured databases
  doctrine:fixtures:load              Load data fixtures to your database.
  doctrine:generate:crud              Generates a CRUD based on a Doctrine entity

  doctrine:generate:entity            Generates a new Doctrine entity inside a bundle
  doctrine:generate:form              Generates a form type class based on a Doctrine entity
  doctrine:mapping:import             Imports mapping information from an existing database

为什么没有来自

的任务

doctrine:schema

命名空间？

这是我的AppKernel.php的一部分：

   $bundles = array(
        new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
        new Symfony\Bundle\SecurityBundle\SecurityBundle(),
        new Symfony\Bundle\TwigBundle\TwigBundle(),
        new Symfony\Bundle\MonologBundle\MonologBundle(),
        new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
        new Symfony\Bundle\AsseticBundle\AsseticBundle(),
        new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
        new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
        new JMS\AopBundle\JMSAopBundle(),
        new JMS\DiExtraBundle\JMSDiExtraBundle($this),
        new JMS\SecurityExtraBundle\JMSSecurityExtraBundle(),
        new Knp\Bundle\MenuBundle\KnpMenuBundle(),
        new Sonata\CacheBundle\SonataCacheBundle(),
        new Sonata\BlockBundle\SonataBlockBundle(),
        new Sonata\AdminBundle\SonataAdminBundle(),
        new Sonata\IntlBundle\SonataIntlBundle(),
        new Sonata\DoctrineORMAdminBundle\SonataDoctrineORMAdminBundle(),
        new Sonata\EasyExtendsBundle\SonataEasyExtendsBundle(),
        new Sonata\UserBundle\SonataUserBundle('FOSUserBundle'),
        new Sonata\SeoBundle\SonataSeoBundle(),
        new Sonata\jQueryBundle\SonatajQueryBundle(),
        new Stof\DoctrineExtensionsBundle\StofDoctrineExtensionsBundle(),
        new Doctrine\Bundle\FixturesBundle\DoctrineFixturesBundle(),
        new Doctrine\Bundle\MigrationsBundle\DoctrineMigrationsBundle(),
        new FOS\UserBundle\FOSUserBundle(),
        new Genemu\Bundle\FormBundle\GenemuFormBundle(),
        new Liip\ImagineBundle\LiipImagineBundle(),
        new Knp\Bundle\GaufretteBundle\KnpGaufretteBundle(),
        new Vich\UploaderBundle\VichUploaderBundle(),
        new FOS\JsRoutingBundle\FOSJsRoutingBundle(),
        new Knp\Bundle\PaginatorBundle\KnpPaginatorBundle(),
        new Mopa\Bundle\BootstrapBundle\MopaBootstrapBundle(),
        new HWI\Bundle\OAuthBundle\HWIOAuthBundle(),

        new App\BackendBundle\AppBackendBundle(),
        new App\FrontendBundle\AppFrontendBundle(),
        new App\GeneralBundle\AppGeneralBundle(),
        new App\DemoBundle\AppDemoBundle(),
        new App\CompanyBundle\AppCompanyBundle(),

是否有可能其他捆绑包会覆盖doctrine-bundle中的任务？任何提示修复它将不胜感激。

提前致谢！
