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

Question

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 1

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

Answer 2

Check if console/kernel.php is inside of app-folder, if not it might be inside of your laravelApp.

If so, move console/kernel.php to app-folder.
