Silex and autloading controller classes

I am having problems getting class autoloading to work in the Silex skeleton I am putting together. I have this working in another project, but I can't figure out what I am doing wrong here.
My directory looks like this:


Here is my index.php

$app = require __DIR__.'/../src/app.php';


require_once __DIR__.'/../vendor/autoload.php';
$app = new Silex\Application();
$app['debug'] = true;
$app->get("/hello/{name}", 'App\Controller\HelloController::hello');
return $app;



namespace App\Controller;

use Silex\Application;
use Symfony\Component\HttpFoundation\Response;

class HelloController
public function hello($name)
return new Response('<html><head></head><body><h1>Hello, '.$name.'</h1></body></html>');

and composer.json

"require": {
"silex/silex": "^1.3"
"autoload": {
"psr-4": {
"App\\": "/src"

Whenever I try to open index.php/hello/world in a browser, I get this error:

InvalidArgumentException in ControllerResolver.php line 153:
Class "App\Controller\HelloController" does not exist


Your psr-4 is not working. Add a dot before '/src'

"App\\": "./src"

or move the slash to the end

"App\\": "src/"

or just remove the slash. The path must be relative.
