Deploying Symfony 2.5.7 to heroku cloud - Class 'Doctrine\Bundle\DoctrineBundle\DoctrineBundle' not found

Question

I'm trying to deploy my Symfony app to heroku and am following the Deploying to Heroku tutorial.

However, when I push my code to my heroku app, heroku fails to compile my app and I get the following message after the packages from composer.json get downloaded:

Creating the "app/config/parameters.yml" file

PHP Fatal error: Class 'Doctrine\Bundle\DoctrineBundle\DoctrineBundle' not found in /tmp/build_45216c70c70215d5009d6aaa12fb90c1/app/AppKernel.php on line 16

Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-install-cmd event terminated with an exception

[RuntimeException]
An error occurred when executing the "'cache:clear --no-warmup'" command.

This is the content of my composer.json:

        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::installRequirementsFile",
        "Sensio\\Bundle\\DistributionBundle\\Composer\\ScriptHandler::removeSymfonyStandardFiles"
    ]
},

    "bin-dir": "bin"
},

    },
    "branch-alias": {
        "dev-master": "2.5-dev"
    }
}

When I install the vendors on my local machine, I can find the DoctrineBundle class in vendor/doctrine/doctrine-bundle/Doctrine/Bundle/DoctrineBundle/DoctrineBundle.php, so I don't understand this error :-(....

Thank you

This is due to a long-standing issue in Symfony, see https://github.com/symfony/symfony/pull/12784

You need to upgrade Symfony to 2.5.8 or newer, or 2.6.1 or newer.

Also make sure you've set SYMFONY_ENV to prod in heroku config.
