可捕获的致命错误:参数1传递给ShopBundleControllerHomepageController::__c

我试图覆盖HomepageController:indexAction从SyliusShopBundle传递一些数据到index.html.twig，但一个例外不断出现:

可捕获的致命错误:参数1传递给AppBundle'Controller'CustomHomepageController::__construct()必须是Symfony'Bundle'FrameworkBundle' template 'EngineInterface的一个实例，没有给出，在C:'wamp3'www'acme'app'cache'dev'appDevDebugProjectContainer.php中调用，并在1619行定义

AppBundle/控制器/CustomHomepageController.php:

<?php
    namespace AppBundle'Controller;
    use Symfony'Bundle'FrameworkBundle'Templating'EngineInterface;
    use Symfony'Component'HttpFoundation'Request;
    use Sylius'Bundle'ShopBundle'Controller'HomepageController as          baseHomepageController;

    class CustomHomepageController extends baseHomepageController
    {
    /**
    * @var EngineInterface
    */
    private $templatingEngine;
   /**
 * @return EngineInterface
 */
public function getTemplatingEngine()
{
    return $this->templatingEngine;
}
/**
 * @param EngineInterface $templatingEngine
 */
public function __construct(EngineInterface $templatingEngine)
{
    $this->templatingEngine = $templatingEngine;
}
/**

public function indexAction(Request $request)
{
    //var_dump($request);
    $s = "test";
    return $this->templatingEngine->renderResponse('SyliusShopBundle:Homepage:index.html.twig',array("data"=>$s));
}
}
