I'm trying to configure travis to run grumphp without success... I get the following error:

PHP Fatal error:  Uncaught exception 'ReflectionException' with message 'Class GrumPHP\Task\Phpcpd does not exist' in /home/travis/build/trovit/php-code-validator/vendor/symfony/dependency-injection/ContainerBuilder.php:845
