[FIXED] Symfony 4 : The file was found but the class was not in it

Issue

this problem has been asked a lot but none of the answer could help me. I'm doing a symfony 4 upgrade of an outdated symfony 3. I removed all the bundle to have to correct file architecture but i probably messed something up.

Just doing bin/console in the command line I get this error :

The autoloader expected class "App\Controller\BrandAcadamyFeedback\FeedbackAnswerController" to be defined in file "/Users/username/www/myfolder/sf/vendor/composer/../../src/Controller/BrandAcadamyFeedback/FeedbackAnswerController.php". The file was found but the class was not in it, the class name or namespace probably has a typo in /Users/username/www/myfolder/sf/config/services.yaml (which is loaded in resource "/Users/username/www/myfolder/sf/config/services.yaml").

Here are my files :

Services.yaml

imports:
- { resource: security.yaml }

parameters:
   locale: 'en'

services:
    _defaults:
        autowire: true      
        autoconfigure: true 
        public: false

    App\:
        resource: '../src/*'
        exclude: '../src/{Entity,Migrations,Tests,Kernel.php}'

    App\Controller\:
        resource: '../src/Controller/*'
        tags: ['controller.service_arguments']

FeedbackAnswerController.php

namespace App\Controller\BrandAcadamyFeedback;

use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Validator\ConstraintViolationList;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\ParamConverter;
use Symfony\Component\Routing\Annotation\Route;
use FOS\RestBundle\Controller\Annotations\View;
use FOS\RestBundle\Controller\Annotations\Post;
use Nelmio\ApiDocBundle\Annotation\ApiDoc;
use App\Controller\API\APIController;

/**
* Controller for Entity\BrandAcadamyFeedback\FeedbackAnswer.
*
* @View
* @Route("/api/feedback-answer")
*/
class FeedbackAnswerController extends APIController
{
}

Annotations.yaml

controllers:
    resource: ../../src/Controller/
    type: annotation

Composer.json

"autoload": {
    "psr-4": {
        "App\\": "src/"
    }
}

It's probably something easy but couldn't figure it out, nor find an answer online.

Any help would be highly appreciated. I hope I gave enough information.

Solution

Thanks to Cerad comment I went and quadruple check the namespace for my controllers and there was indeed an error spell in the folder name of my app.

"App\Controller\BrandAcadamyFeedback\" should have been App\Controller\BrandAcademyFeedback\

Sorry.
