My event listener doesn't work from my reusable bundle in Symfony 4.1

Short story : I have some diffulties to use a listener properly on my custom "vendor" bundle.

I'm coding a reusable bundle for Symfony 4.1 framework (for managing Users). I put the whole bundle in this location of a new symfony project : myproject/lib/AcmeUserBundle/src/

Just like this Demo

Because my bundle is at a non usual place, I changed my config/services.yaml like this (in case this is relevent) :

services:    # default configuration for services in *this* file    _defaults:        autowire: true        autoconfigure: true        public: false          App\:        resource: '../src/*'        exclude: '../src/{DependencyInjection,Entity,Migrations,Tests,Kernel.php}'    App\Controller\:        resource: '../src/Controller'        tags: ['controller.service_arguments']    Acme\UserBundle\:        resource: '../lib/AcmeUserBundle/src/*'        exclude: '../lib/AcmeUserBundle/src/{DependencyInjection,Entity,Migrations,Tests}'    Acme\UserBundle\Controller\:        resource: '../lib/AcmeUserBundle/src/Controller'        tags: ['controller.service_arguments']

Then, I coded a login form (that you don't care much), and when a user logged in, I want to update his last datetime connexion info in database. So I have built a listener following this tutorial on the security.interactive_login event :

<?phpnamespace Acme\UserBundle\EventListener;use DateTime;use Doctrine\ORM\EntityManagerInterface;use Symfony\Component\Security\Http\Event\InteractiveLoginEvent;class LoginListener{    /**     * @var EntityManagerInterface     */    private $entityManager;    /**     * LoginListener constructor.     *     * @param EntityManagerInterface $entityManager     */    public function __construct(EntityManagerInterface $entityManager)    {        $this->entityManager = $entityManager;    }    /**     * @param InteractiveLoginEvent $event     */    public function onSecurityInteractiveLogin(InteractiveLoginEvent $event)    {        // Get the User entity.        $user = $event->getAuthenticationToken()->getUser();        /** @var \Acme\UserBundle\Entity\User $user */        $user->setLastLoggedAt(new DateTime());        $this->entityManager->persist($user);        $this->entityManager->flush();    }}

lib/AcmeUserBundle/src/Resources/config/services.yaml looks like :

services:    Acme\UserBundle\EventListener\LoginListener:        tags:            - { name: kernel.event_listener, event: security.interactive_login }

lib/AcmeUserBundle/src/DependencyInjection/AcmeUserExtension.php looks like :

class AcmeUserExtension extends Extension{    /**     * @param array            $configs     * @param ContainerBuilder $container     */    public function load(array $configs, ContainerBuilder $container)    {        $loader = new YamlFileLoader(            $container,            new FileLocator(__DIR__.'/../Resources/config')        );        $loader->load('services.yaml');    }}

I can see my service using these symfony commands :php bin/console debug:autowiringphp bin/console debug:containerBut I can't see anything with :php bin/console debug:event-dispatcher

When I log-in with my user, no error occurs, and of course, no date is inserted in database. That's why I think my listener is not properly registered.

Any idea why ?

EDIT after Cerad's comment :

Output of php bin/console debug:container LoginListener

 ---------------- ------------------------------------------------  Option           Value ---------------- ------------------------------------------------  Service ID       Acme\UserBundle\EventListener\LoginListener  Class            Acme\UserBundle\EventListener\LoginListener  Tags             -  Public           no  Synthetic        no  Lazy             no  Shared           yes  Abstract         no  Autowired        yes  Autoconfigured   yes ---------------- ------------------------------------------------

We can see that the Tags part is empty. That's the reason why my listener is ignored.And... it works if I comment that part of my config/service.yaml :

...    #Acme\UserBundle\:    #    resource: '../lib/AcmeUserBundle/src/*'    #    exclude: '../lib/AcmeUserBundle/src/{DependencyInjection,Entity,Migrations,Tests}'...

New output of php bin/console debug:container LoginListener

 ---------------- -----------------------------------------------------------  Option           Value ---------------- -----------------------------------------------------------  Service ID       Acme\UserBundle\EventListener\LoginListener  Class            Acme\UserBundle\EventListener\LoginListener  Tags             kernel.event_listener (event: security.interactive_login)  Public           no  Synthetic        no  Lazy             no  Shared           yes  Abstract         no  Autowired        no  Autoconfigured   no ---------------- -----------------------------------------------------------

Tags is now correct and my listener works properly
