Symfony deploy PHP fatal error: Class not found in AppKernel.php

Question

So.. Ive been building an application with Symfony3 framework for my bachelor project and it works flawless on localhost. Both in dev-environment and prod.

However. When Im trying to deploy it to a Heroku App im getting the following log..

!     Push failed

Or at least this is where it starts to go wrong.

My AppKernel.php file looks like this..

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 Doctrine\Bundle\MigrationsBundle\DoctrineMigrationsBundle(),
                new \Doctrine\Bundle\DoctrineCacheBundle\DoctrineCacheBundle(),
                new AppBundle\AppBundle(),
            ];

            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();
                $bundles[] = new Sensio\Bundle\GeneratorBundle\SensioGeneratorBundle();
                $bundles[] = new Doctrine\Bundle\FixturesBundle\DoctrineFixturesBundle();
            }

            return $bundles;
        }

If I comment out the Swiftmailer class in AppKernel, another class is causing the exact same issue.

I hope theres someone here who can help me out or at least to understand the error a bit more.

Truth be told, deploying applications and handling anything serverside is not my strongest site so im in pretty deep water.

Thanks... :)

Have you looked at this at all: symfony.com/doc/current/deployment/heroku.html — Alvin Bunk

@AlvinBunk Yes i have gone through both the symfony tut and the heroku one, but it seems like I'm missing some configurations or something which i cannot figure out...? — Claus Marin Kaiser

@GopalJoshi That is what I stumbled upon now as well. But when Im updating i get the following error: Content-Length mismatch http://packagist.org could not be fully loaded, package information was loaded from the local cache and may be out of date — Claus Marin Kaiser
– Claus Marin Kaiser, Commented Dec 12, 2016 at 9:59
please check permission of cache folder. Reference github.com/composer/composer/issues/3470 — Gopal Joshi

I'm beginning to think it's a file permission issue as well like Gopal. Here's the documentation on file permissions that need to be set:

https://symfony.com/doc/current/setup/file_permissions.html

Heroku is a bit different, so I don't have any guidance on that since I haven't tried it before.

@AlvinBunk I've reensured the permissions in the various folders and established a much more stable internet connection and the previous composer update error is now gone..

However.. Now i get the same error as i do when I'm trying to deploy the app.

  .

Have you contacted Heroku support? Or maybe you have a free account? I'm not sure how support works. I still suspect a file permissions problem.
So. It works now. I deleted and unhooked the swiftmailer bundle everywhere and i succesfully deployed. Afterwards i reenabled and isntalled the bundle again and It seemed like i had an issue with my bundle requirements. I was trying to run composer require swiftmailer/swiftmailer Instead of using composer require symfony/swiftmailer-bundle Thanks for your help though @AlvinBunk
You can help me by upvoting any one of my comments! Glad you got it working!
