Snippet:

class TwigCs extends \GrumPHP\Task\AbstractExternalTask
{
    public static function getConfigurableOptions() : \_HumbugBoxdfa46d19239b\Symfony\Component\OptionsResolver\OptionsResolver
    {
        $resolver->setDefaults(
            [
                //.....
                'ruleset'      => '_HumbugBoxdfa46d19239b\\FriendsOfTwig\\Twigcs\\Ruleset\\Official',
                //.....
            ]
         );
        return $resolver;
    }
...

This specific class could be namespaced if it does not break anything else.
