Php 批注不存在，或无法在Symfony中自动加载

当我将Smfony从2.7版本升级到3.2版本时，我遇到了一个我不一定理解的问题。我已经升级了我的

composer.json

中的所有依赖项，以便在symfony更新之后使用。所有依赖项都安装得很好，但是当我进入脚本部分（即清空缓存并安装资产）时，我会遇到这个错误

Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache
PHP Fatal error:  Uncaught exception 'Doctrine\Common\Annotations\AnnotationException' with message '[Semantical Error] The annotation "@Hello\ReleasesBundle\Entity\Package" in class Ubiflow\ReleasesBundle\Controller\PackageController does not exist, or could not be auto-loaded.' in /home/web/gestionnaire/vendor/doctrine/annotations/lib/Doctrine/Common/Annotations/AnnotationException.php:54

我通过添加供应商提供的

autoload.php

文件和删除

bootstrap.cache

更改了这些文件，就像一些Symfony升级教程（app/console、app/AppCache、app/phpunit.xml.dist、web/app.php、web/app_dev.php）中所说的那样

这是

composer.json

是您项目中的一个内部捆绑包吗？确切地说……。您可能忘记了使用批注加载程序。
