I'm new to Symfony. I'm following a course, and after creating a new Symfony project, they use this console to create new bundle php bin/console generate:bundle

But when I do this in the console, and then use php bin/console server:run, it throws an error:

PHP Fatal error: Uncaught Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class "HomeBundle" from namespace "HomeBundle".

Did you forget a "use" statement for another namespace?
in C:\xampp\htdocs\symfony_CRUD\app\AppKernel.php:19

After a lot of time searching for solution, almost i just found "change composer.json" solution, but it already fixed composer.json at Symfony 3.4 , so i don't know what to do next.

Here is my composer.json at the beginning

AppKernel.php

<?php

use Symfony\Component\DependencyInjection\ContainerBuilder;
use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = [
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),

            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new HomeBundle\HomeBundle(),
        ];

        if (in_array($this->getEnvironment(), ['dev', 'test'], true)) {
            $bundles[] = new Symfony\Bundle\DebugBundle\DebugBundle();
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();

            if ('dev' === $this->getEnvironment()) {
                $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
                $bundles[] = new Symfony\Bundle\WebServerBundle\WebServerBundle();
            }
        }

        return $bundles;
    }

    public function getRootDir()
    {
        return __DIR__;
    }

    public function getCacheDir()
    {
        return dirname(__DIR__).'/var/cache/'.$this->getEnvironment();
    }

    public function getLogDir()
    {
        return dirname(__DIR__).'/var/logs';
    }

    public function registerContainerConfiguration(LoaderInterface $loader)
    {
        $loader->load(function (ContainerBuilder $container) {
            $container->setParameter('container.autowiring.strict_mode', true);
            $container->setParameter('container.dumper.inline_class_loader', true);

            $container->addObjectResource($this);
        });
        $loader->load($this->getRootDir().'/config/config_'.$this->getEnvironment().'.yml');
    }
}

Please help, thanks :)

Look like you have an unknown class in your AppKernel.php line 19. Can you show your AppKernel ? Do you have a bundle called HomeBundle ? maybe you remove it ? Your composer.json look okDavid Courtey
yes i will, please stand by, thanks for reading :)fudu
i've edited the post, please check :) by the way, this is totally a new symphony project, so i don't think AppKernel have any problems :)fudu
Please note for future questions that the framework you are using is called Symfony, and not Symphony (which is an unrelated CMS). Thanks :) I've edited the question and tag.David Oliver
Yes, thanks for telling me that :) I'll remember for the next timefudu

Ok I see now, you should change this in your composer.json, from :

"autoload": {
    "psr-4": {
        "AppBundle\\": "src/AppBundle"
    },
   "classmap": [ "app/AppKernel.php", "app/AppCache.php" ]
},

to

"autoload": {
    "psr-4": {
        "": "src/"
    },
   "classmap": [ "app/AppKernel.php", "app/AppCache.php" ]
},

Like this you add to the composer autoloader (vendor/autoload.php) all php class inside src/ of your project

After this you need to recreate your autoload file:

composer dump-autoload
