Q:

Laravel - can't install from my source control

I need to automate my laravel project setup/upgrade  on my production machine from source control.
I wrote a bash script to clone the source from the GIT repo and run the setup.
The git code is going to the folder /var/www/prod/mainapp/, so the following bash code is running after the git command:
cd /var/www/prod/mainapp/app/
composer install # composer update will not work as well
php artisan dump-autoload
php artisan optimize

I am getting the following error when the code reaches to: php artisan optimize
PHP Fatal error:  Class 'App\Providers\SocialUserProvider' not found in /var/www/prod/mainapp/app/vendor/laravel/framework/src/Illuminate/Foundation/ProviderRepository.php on line 146
in my app.php i have the following providers:
    App\Providers\FacebookGraphProvider::class,
    Torann\GeoIP\GeoIPServiceProvider::class,
    App\Providers\SocialUserProvider::class,

this is my composer.json:

    "keywords": ["framework", "laravel"],
    "license": "MIT",
    "type": "project",

        "laravel/framework": "5.2.*",
        "torann/geoip": "0.2.3"
    },
    "require-dev": {
        "fzaninotto/faker": "~1.4",

    },
    "autoload": {
        "classmap": [
            "database",
            "app/Facades",
             "app/Services"
        ],
        "psr-4": {
            "App\\": "app/"
        }
    },
    "autoload-dev": {
        "classmap": [
            "tests/TestCase.php"
        ]
    },
    "scripts": {
        "post-root-package-install": [
            "php -r \"copy('.env.example', '.env');\""
        ],
        "post-create-project-cmd": [
            "php artisan key:generate"
        ],
        "post-install-cmd": [
            "Illuminate\\Foundation\\ComposerScripts::postInstall",
            "php artisan optimize"
        ],
        "post-update-cmd": [
            "Illuminate\\Foundation\\ComposerScripts::postUpdate",
            "php artisan optimize"
        ]
    },
    "config": {
        "preferred-install": "dist"
    }
}

A:

You need to add to the classmap the line that will tell who should be autoloaded. app/Providers
"classmap": [
        "database",
        "app/Facades",
         "app/Services",
         "app/Providers" //this is the missing part.
    ]
