Symfony2 Composer Bundle Namespace

Question

I'm trying for a while to import an own bundle via composer but I got a few problems. I got following bundle:

<?php

namespace Platform\Bundle\PollBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class PlatformPollBundle extends Bundle
{
}

The bundle is in vendor/platform/pollbundle/.

In the "main" composer.json I definied the namespace for autoloading:

"autoload": {
    "psr-0": {
        "": "src/" ,
        "Platform\\": "vendor/platform"
    }
},

and in the composer.json from the bundle I definied:

{
    "name" : "platform/pollbundle",
    "type": "symfony-bundle",
    "extra": {
        "servicePath": ""
    },
    "autoload": {
        "psr-0": {
            "Platform\\Bundle\\PollBundle": ""
        }
    },
    "target-dir": "pollbundle"

}

In the autoload_namespaces there is correctly following line:

'Platform\\' => array($vendorDir . '/platform'),

But I got the error:

Fatal error: Class 'Platform\Bundle\PollBundle\PlatformPollBundle' not found in     ........Controller.php on line 13

I tried about 100 solutions but nothing works. Would be great if somebody can help me.

Bundles aren't loaded by composer, but instead are handled by the Symfony kernel itself. In the app directory, edit AppKernel.php like this:

public function registerBundles()
{
    $bundles = array(
        new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
        ...,
        new Platform\Bundle\PollBundle\PlatformPollBundle()//<-- add this
    );
}

In the app/autoload.php file, meanwhile, register the new namesepace. It used to be done through the $loader instance, by calling $loader->registerNameSpaces(), but now, you have to call a static method on the AnnotationRegistry class:

AnnotationRegistry::registerAutoloadNamespace('PollBundle', 'path/to/PollBundle');

A hacky fix I suggested, which is apparently what fixed it for you, would be to run php app/console generate:bundle in the console, to generate a new bundle with the same name, and then simply replace that bundle's directory (in src/) with your bundle.

It is wrong to define ANY autoloading in the main application for anything pointing into the vendor folder! That's what composer is for. Composer will read the autoload declaration for every package contained in there and add the appropriate autoloading automatically. There is no need to add this yourself.

And even if you have to use software that didn't yet add a composer.json file, the autoloading of only that package should go into the package definition block, not into the autoload definition.
