Laravel error 'ReflectionException' - 'Class App\Http\Kernel does not exist'

I was trying to go live with a laravel project i developped a year back in school and i ran into some issue.
After uploading the whole project on my hosting service's server, i got these errors on my browser as well as on my SSH shell.


Fatal error: Uncaught exception 'ReflectionException' with message 'Class App\Http\Kernel does not exist' in /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php:779
Stack trace: #0 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php(779): ReflectionClass->__construct('App\Http\Kernel') #1 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php(659): Illuminate\Container\Container->build('App\Http\Kernel', Array) #2 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Foundation/Application.php(644): Illuminate\Container\Container->make('App\Http\Kernel', Array) #3 /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php(229): Illuminate\Foundation\Application->make('App\Http\Kernel', Array) #4 /home/clients/ffa41f94063 in /home/clients/ffa41f94063541f86a0fe6602a73caa1/myforms/vendor/laravel/framework/src/Illuminate/Container/Container.php on line 779


I think it could be related to my namespace configuration, because i haven't all understood yet.

Here is my composer.json file :



{
"name": "laravel/laravel",
"description": "The Laravel Framework.",
"keywords": ["framework", "laravel"],
"license": "MIT",
"type": "project",
"require": {
"laravel/framework": "5.0.*",
"illuminate/html": "5.*",
"barryvdh/laravel-dompdf": "0.5.*",
"guzzlehttp/guzzle": "~4.0"

},
"require-dev": {
"phpunit/phpunit": "~4.0",
"phpspec/phpspec": "~2.1"
},
"autoload": {
"classmap": [
"database"
],
"psr-4": {
"App\\": "myforms/app/"
}
},
"autoload-dev": {
"classmap": [
"tests/TestCase.php"
]
},
"scripts": {
"post-install-cmd": [
"php artisan clear-compiled",
"php artisan optimize"
],
"post-update-cmd": [
"php artisan clear-compiled",
"php artisan optimize"
],
"post-create-project-cmd": [
"php -r \"copy('.env.example', '.env');\"",
"php artisan key:generate"
]
},
"config": {
"preferred-install": "dist"
}
}





What I have already done :


  • Delete /vendor and make a new install with
    composer install

  • composer dump-autoload

  • composer update

    btw, I get the error when I insert the
    composer update



Please inform me if i should post another file that could be useful.

Thanks in advance for your help.

Answer

In composer.json change:

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

to:

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

On the server, in your source directory, run composer update then composer dump-autoload

PSR-4 in Laravel looks for namespaces relative to the root of the project
