Things to be aware of when pulling: Joomla creates a cache of the namespaces of its extensions in JOOMLA_ROOT/administrator/cache/autoload_psr4.php. If extensions are created, deleted or removed in git then this file needs to be recreated. You can simply delete the file and it will be regenerated on the next call to Joomla.
