    // We need to change the app.root in order to generate packages into

    // the virtual file system. Unfortunately, here we can't just use

    // $this->container->setParameter(), because by this time the parameter bag

    // is frozen. Also, we can't use ::register() method for this as it is

    // expected by Kernel tests, because this value gets overridden during

    // setUp() method. So we have to recreate the container instance with

    // the same values but the new app.root value.

    $container = new ContainerBuilder(new FrozenParameterBag([

        'app.root' => 'vfs://drupal',

    // Find out where package will be exported.
