Autoloader expected class Symfony2

Question

I'm using symfony 2.3 framework and the autoloader claims to have found the file but no class:

RuntimeException: The autoloader expected class "Sensio\Bundle\
FrameworkExtraBundle\Request\ParamConverter\DateTimeParamConverter" 
to be defined in file "/home/na/auth/vendor/sensio/framework-extra-bundle/
Sensio/Bundle/FrameworkExtraBundle/Request/ParamConverter/
DateTimeParamConverter.php". The file was found but the class was not in it, 
the class name or namespace probably has a typo.

The file this is refering to is shown bellow:

<?php

/*
 * This file is part of the Symfony framework.
 *
 * (c) Fabien Potencier <[email protected]>
 *
 * This source file is subject to the MIT license that is bundled
 * with this source code in the file LICENSE.
 */

namespace Sensio\Bundle\FrameworkExtraBundle\Request\ParamConverter;

use Sensio\Bundle\FrameworkExtraBundle\Configuration\ConfigurationInterface;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpKernel\Exception\NotFoundHttpException;
use DateTime;

/**
 * Convert DateTime instances from request attribute variable.
 *
 * @author Benjamin Eberlei <[email protected]>
 */
class DateTimeParamConverter implements ParamConverterInterface
{
    /**
     * @{inheritdoc}
     * 
     * @throws NotFoundHttpException When invalid date given
     */
    public function apply(Request $request, ConfigurationInterface $configuration)
    {
        $param = $configuration->getName();

        if (!$request->attributes->has($param)) {
            return false;
        }

        $options = $configuration->getOptions();
        $value   = $request->attributes->get($param);

        $date = isset($options['format'])
            ? DateTime::createFromFormat($options['format'], $value)
            : new DateTime($value);

        if (!$date) {
            throw new NotFoundHttpException('Invalid date given.');
        }

        $request->attributes->set($param, $date);

        return true;
    }

    /**
     * @{inheritdoc}
     */
    public function supports(ConfigurationInterface $configuration)
    {
        if (null === $configuration->getClass()) {
            return false;
        }

        return "DateTime" === $configuration->getClass();
    }
}

Anyway, some detail that might help was that I recently installed Doctrine and ran the commands ...

 2028  php app/console doctrine:schema:create
 2029  php app/console doctrine:generate:entities Auth

After those commands, symfony stopped working. I don't know if this is some weird bug or something. If you need more information, I can post. Thanks for any help.

Answer 1

Missing (or short) PHP opening tag can cause that error too. Yes it sounds funny, but if you just follow Symfony example and copy/paste whole class you may not notice that (as I didn't).

Answer 2

This is a little old now, but in case anyone else gets here by search: This is undoubtedly a cache issue. Manually delete the contents of app/cache/dev and app/cache/prod, and everything should resolve.

Answer 3

If anyone else has this issue and it doesn't go away by clearing the cache, then I recommend removing the entire folder with your composer dependencies and re-executing composer install.

It worked for me :) .
