AppKernel.php strange thing - php

Question

Im trying to set up new project in Symfony. When I added my own Bundle I have this strange thing appear:
PHP Fatal error: Uncaught Symfony\Component\Debug\Exception\ClassNotFoundException: Attempted to load class "ContactBoxBundle" from namespace "ContactBoxBundle".
Did you forget a "use" statement for another namespace? in /home/doro/projects/ContactBox/app/AppKernel.php:18
Stack trace:
0 /home/doro/projects/ContactBox/vendor/symfony/symfony/src/Symfony/Component/HttpKernel/Kernel.php(450): AppKernel->registerBundles()

4 /home/doro/projects/ContactBox/vendor/symfony/symfony/src/Symfony/Component/Console/Applicati in /home/doro/projects/ContactBox/app/AppKernel.php on line 18
My AppKernel looks like that:
<?php
use Symfony\Component\HttpKernel\Kernel;
use Symfony\Component\Config\Loader\LoaderInterface;
class AppKernel extends Kernel
{
public function registerBundles()
{
$bundles = [
new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
new Symfony\Bundle\SecurityBundle\SecurityBundle(),
new Symfony\Bundle\TwigBundle\TwigBundle(),
new Symfony\Bundle\MonologBundle\MonologBundle(),
new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
new ContactBoxBundle\ContactBoxBundle(),
];
if (in_array($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)
{
$loader->load($this->getRootDir().'/config/config_'.$this->getEnvironment().'.yml');
}
}
And I seriously have no idea what is going on, its first time when its happend to me and I made new projects before in Symfony. Any ideas?

Answer 1

What is the namespace of your bundle in the file : ContactBoxBundle/ContactBoxBundle.php ?
Refering here, the bundle name AcmeTestBundle is in the namespace namespace Acme\TestBundle; then the appKernel is new Acme\TestBundle\AcmeTestBundle(),.
Maybe that's your problem.
