symfony2: class included in AppKernel can not be found

Question

I have this app/AppKernel:

<?php

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

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        $bundles = array(
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new Symfony\Bundle\SecurityBundle\SecurityBundle(),
            new Symfony\Bundle\TwigBundle\TwigBundle(),
            new Symfony\Bundle\MonologBundle\MonologBundle(),
            new Symfony\Bundle\SwiftmailerBundle\SwiftmailerBundle(),
            new Symfony\Bundle\AsseticBundle\AsseticBundle(),
            new Doctrine\Bundle\DoctrineBundle\DoctrineBundle(),
            new Sensio\Bundle\FrameworkExtraBundle\SensioFrameworkExtraBundle(),
            new JMS\AopBundle\JMSAopBundle(),
            new JMS\DiExtraBundle\JMSDiExtraBundle($this),
            new JMS\SecurityExtraBundle\JMSSecurityExtraBundle(),
            new JMS\I18nRoutingBundle\JMSI18nRoutingBundle(),
            new FOS\UserBundle\FOSUserBundle(),
            new Sports\FrontendBundle\SportsFrontendBundle(),   // line 25             
            new Sports\UserBundle\SportsUserBundle(),
            new Sonata\DefaultBundle\SonataDefaultBundle(),
            new Sonata\DoctrineORMAdminBundle\SonataDoctrineORMAdminBundle(),
            new Sonata\AdminBundle\SonataAdminBundle(),
            new Sonata\BlockBundle\SonataBlockBundle(),
            new Sonata\CacheBundle\SonataCacheBundle(),
            new Knp\Bundle\MenuBundle\KnpMenuBundle(),
            new Stof\DoctrineExtensionsBundle\StofDoctrineExtensionsBundle()
        );

        if (in_array($this->getEnvironment(), array('dev', 'test'))) {
#$bundles[] = new Acme\DemoBundle\AcmeDemoBundle();
            $bundles[] = new Symfony\Bundle\WebProfilerBundle\WebProfilerBundle();
            $bundles[] = new Sensio\Bundle\DistributionBundle\SensioDistributionBundle();
            $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
        }

        return $bundles;
    }

    public function registerContainerConfiguration(LoaderInterface $loader)
    {
        $loader->load(__DIR__.'/config/config_'.$this->getEnvironment().'.yml');
    }

And this class src/Sports/FrontendBundle/SportsFrontendBundle.php:

namespace Sports\FrontendBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class SportsFrontendBundle extends Bundle
{
}

And Im getting this error:

Fatal error: Class 'Sports\FrontendBundle\SportsFrontendBundle' not found in /home/tirengarfio/programacion/sports/app/AppKernel.php on line 25

This is my app/autoload.php:

<?php

use Doctrine\Common\Annotations\AnnotationRegistry;

if (!$loader = @include __DIR__.'/../vendor/autoload.php') {

    $message = <<< EOF
<p>You must set up the project dependencies by running the following commands:</p>
<pre>
    curl -s http://getcomposer.org/installer | php
    php composer.phar install
</pre>

EOF;

    if (PHP_SAPI === 'cli') {
        $message = strip_tags($message);
    }

    die($message);
}

// intl
if (!function_exists('intl_get_error_code')) {
    require_once __DIR__.'/../vendor/symfony/symfony/src/Symfony/Component/Locale/Resources/stubs/functions.php';

    $loader->add('', __DIR__.'/../vendor/symfony/symfony/src/Symfony/Component/Locale/Resources/stubs');
    $loader->add('Sports',   __DIR__ . '/../src');
}

AnnotationRegistry::registerLoader(array($loader, 'loadClass'));

return $loader;

and my composer.json:

Any idea?

For future references, similar issues can happen if you checkout your code and copy the vendor folder directly without running composer.

To rule autoload issues out, you can simply run install in your symfony2 folder ( assuming you have composer.phar there ):

php composer.phar install

This will install the project dependencies from the composer.lock file if present, or fall back on the composer.json.
