Including a Symfony bundle from a subtree : how to expand autoload path?

Question

I'm using a bundle from a subtree, so I can't modify the structure nor the placement of it. I currently am trying to get it included in autoloading process, and am failing miserably with the "class not found" error message. Currently, my project tree (made with Symfony 3.2) is :

|- app
|- src
    |- MyappBundle
    |- external
         |- Author
             |-UserBundle
                |- Controller
                |- [...]
                |- AuthorUserBundle.php

AuthorUserBundle.php contains :

namespace Author\UserBundle;

use Symfony\Component\HttpKernel\Bundle\Bundle;

class AuthorUserBundle extends Bundle
{
}

To include this bundle, I added in app/AppKernel.php :

new Author\UserBundle\AuthorUserBundle(),

I also added to app/autoload.php, before AnnotationRegistry::registerLoader :

$loader->add('Author',__DIR__.'/../src/external');

I don't master the namespaces imbrications, especially regarding the depth of call, but I tried many variations in autoload.php (like '/../src/external/Author') or AppKernel.php (Author\UserBundle\AuthorUserBundle\AuthorUserBundle()) ending all with the same error message "Class not found".

What did I miss ?

Sorry for the newbie question, I tried alone first, thank you for your time.

P.S. : the external directory can't be removed, the git subtree process doesn't allow to operate in a non empty directory.

Answer 1

You shouldn't use git subtree to include 3rd party code. Add a composer.json to your AuthorUserBundle with all needed autoloading and dependencies. A minimal example (replace ^3.0 with ^2.7 if you still use Symfony 2.7/2.8):

{
    "name": "author/user-bundle",
    "license": "proprietary",
    "type": "library",
    "require": {
        "symfony/framework-bundle": "^3.0"
    },
    "autoload": {
        "psr-4": {
            "Author\\UserBundle\\": ""
        },
    }
}

And require it in your main project as private repository. Please add git tags to and follow semantic versioning.

Assuming your bundle is then called author/user-bundle (composer name), add the following to your projects composer.json:

{
    "require": {
        "author/user-bundle": "^1.0"
    },
    "repositories": [
        {
            "type": "vcs",
            "url":  "[email protected]/user-bundle.git"
        }
    ]
}

Edit 1: added composer.json for AuthorUserBundle repository.

Answer 2

I would give a try to addPsr4 method instead

$loader->addPsr4('Author\\UserBundle\\', __DIR__.'/../src/external/Author/UserBundle');
