Laravel Class 'App\Modules\ServiceProvider' not found?

I'm pretty newbie in creating a package. The first time after I created the following structure, I put it in Vendor folder.

qplot
    environment-color
        src
            config
            QPlot
                EnvironmentColor
                    ColorServiceProvider.php
                    EnvironmentColor.php
        tests

But soon I realized this doesn't make sense, since Laravel won't autoload all the bundles for you unless you registered it. So I moved folder to /app/vendor (new folder).

And then following Andreyco's suggestion to notify autoload path

"autoload": {
    "classmap": [
        "app/commands",
        "app/controllers",
        "app/models",
        "app/vendor",
        "app/database/migrations",
        "app/database/seeds",
        "app/tests/TestCase.php"
    ]
},

And then when I run php artisan dump-autoload, and open vendor/composer/autoload_classmap.php, all new classes under QPlot are registered :)

Now when I go back to add the provider to Laravel /app/config/app.php,

'providers' => array(
    'QPlot\EnvironmentColor\ColorServiceProvider'

So the steps are

• setup your package in a folder where your git will cover
• register the autoload in composer
• composer dump-autoload
• add provider to config
• now go back to coding

Add this to composer.json autoload section:

"psr-4": {
    "App\\": "app/"
}

and then composer dump-autoload

I try run your code, and everything works great.

It's a new installation of Laravel 4.1

Obs.: check your vendor/composer/autoload_classmap.php

<?php

// autoload_classmap.php @generated by Composer

$vendorDir = dirname(dirname(__FILE__));
$baseDir = dirname($vendorDir);

return array(
    'App\\Modules\\Points\\ServiceProvider' => $baseDir . '/app/modules/points/ServiceProvider.php',
    'App\\Modules\\ServiceProvider' => $baseDir . '/app/modules/ServiceProvider.php',
    'BaseController' => $baseDir . '/app/controllers/BaseController.php',
    'DatabaseSeeder' => $baseDir . '/app/database/seeds/DatabaseSeeder.php',
    'HomeController' => $baseDir . '/app/controllers/HomeController.php',
    'IlluminateQueueClosure' => $vendorDir . '/laravel/framework/src/Illuminate/Queue/IlluminateQueueClosure.php',
    'SessionHandlerInterface' => $vendorDir . '/symfony/http-foundation/Symfony/Component/HttpFoundation/Resources/stubs/SessionHandlerInterface.php',
    'TestCase' => $baseDir . '/app/tests/TestCase.php',
    'User' => $baseDir . '/app/models/User.php',
);

  public function register() {

    if ($module = $this->getModule(func_get_args())) {
      $this->app["config"]->package("app/" . $module, app_path() . "/modules/" . $module . "/config");

        // Add routes
      $routes = app_path() . "/modules/" . $module . "/routes.php";
      if (file_exists($routes))
        require $routes;
    }
  }

  public function getModule($args) {
    $module = (isset($args[0]) and is_string($args[0])) ? $args[0] : null;
    return $module;
  }

}

I have the same issue.

The problem was in the file: ./bootstrap/cache/config.php

I have removed it and everything starts to work: rm ./bootstrap/cache/config.php

My infrastructure located in docker I have run that command in the PHP container.
