[Semantical Error] The annotation "@Template" in method
AppBundle\Controller\DefaultController::indexAction() was never
imported. Did you maybe forget to add a "use" statement for this
annotation? in /var/www/symfony_learn_2_6/src/AppBundle/Controller/
(which is being imported from
"/var/www/symfony_learn_2_6/app/config/routing.yml").
Recently while working on symfony I encountered above error.The resolution is simple we just need to add Sensio annotation handler for the above annotation.So in this case since annotation handler for template is missing we need to add
Sensio\Bundle\FrameworkExtraBundle\Configuration\Template
above the controller.Similerly if annotation handler for route is missing then we can add
Sensio\Bundle\FrameworkExtraBundle\Configuration\Route
