Не удается запустить Maven Google Standard App Engine 1.9.68 Archetype

Пытаюсь обновить до последней версии 1.9.68, но не могу найти зависимости. Очень плохо, так как он был выпущен 12 дней назад https://cloud.google.com/appengine/docs/standard/java/release-notes#october_25_2018

При запуске архетипа:
