Question

我有以下服务（仅限）：

# app/config/services.yml
services:
    app.google_service_gmail.watcher_manager:
        class: AppBundle\Provider\Google\Service\Gmail\Watch\WatcherManager

    app.google_service_gmail.mail_watcher:
        class: AppBundle\Provider\Google\Service\Gmail\Watch\MailWatcher
        tags:
            - { name: app.watcher }

我有WatcherManager课程：

namespace AppBundle\Provider\Google\Service\Gmail\Watch;

class WatcherManager
{

    /**
     * @var WatcherInterface[]
     */
    private $watchers = [];

    /**
     * Add a Watcher
     *
     * @param WatcherInterface $watcher
     *
     * @return WatcherManager
     */
    public function addWatcher(WatcherInterface $watcher)
    {
        $this->watchers[] = $watcher;

        return $this;
    }
}

以下编译器传递类：

namespace AppBundle\DependencyInjection\CompilerPass;

use ...

class WatcherCompilerPass implements CompilerPassInterface
{

    /**
     * @inheritdoc
     */
    public function process(ContainerBuilder $container)
    {
        if (!$container->has('app.google_service_gmail.watcher_manager')) {
            return;
        }

        $definition = $container->findDefinition(
            'app.google_service_gmail.watcher_manager'
        );

        $taggedServices = $container->findTaggedServiceIds(
            'app.watcher'
        );

        foreach ($taggedServices as $id => $tags) {
            $definition->addMethodCall('addWatcher', [new Reference($id)]);
        }
    }
}

注册编译器传递：

namespace AppBundle;

use ...

class AppBundle extends Bundle
{

    /**
     * @inheritdoc
     */
    public function build(ContainerBuilder $container)
    {
        parent::build($container);

        $container->addCompilerPass(new WatcherCompilerPass());
    }
}

获取执行任何控制台命令的以下异常：

[Symfony的\元器件\ DependencyInjection \异常\的RuntimeException]
如果参数是对象或资源，则无法转储服务容器。

跨浏览器运行应用程序：

XmlDumper.php第355行中的RuntimeException：如果参数是对象或资源，则无法转储服务容器。

我查看了symfony文档：

并且代码完全相同。

如果我禁用此行代码：

$definition->addMethodCall('addWatcher', [new Reference($id)]);

一切正常。 任何想法？

在Symfony2中使用标记服务的Bug
