Hi,

I'm having trouble (auto)loading Sylius.
Sylius/Sylius#1411
#10201

Basically the File Path Validation in the DebugClassLoader should work but since it compares the full path and not the subset it fails

Sylius\Component\Cart\SyliusCartEvents vs (...)/vendor/sylius/cart/SyliusCartEvents.php

while in the composer.json the following exists:

"autoload": {
        "psr-4": { "Sylius\\Component\\Resource\\": "" }
    },

I am using the 2.5 Version

To get it working I now added a small Code Snippet:

        if ($file) {
            if ('\\' == $class[0]) {
                $class = substr($class, 1);
            }

            $classPart = $class;

            /*
             * check if this is a PSR-4 based class
             */
            if (method_exists($this->classLoader[0], 'getPrefixesPsr4')){
                $psr4Prefixes = $this->classLoader[0]->getPrefixesPsr4();

                /*
                 * get the psr-4 prefix that was used
                 */
                $psr4PathFinder = function ($class) use ($psr4Prefixes){
                    foreach($psr4Prefixes as $prefix => $path){
                        if(strpos($class, $prefix) !== false){
                            return $prefix;
                        }
                    }

                    return false;
                };

                if(($tmp = $psr4PathFinder($class)) !== false){
                    $classPart = str_replace($tmp, '', $class);
                }
            }


            $i = 0;
            $tail = DIRECTORY_SEPARATOR . str_replace('\\', DIRECTORY_SEPARATOR, $classPart).'.php';
            $len = strlen($tail);

It is working without errors for the normal autoloader
