Я не понимаю, как добавить зависимость.

Answer 1

Это означает, что зависимостей com.jme3:xmlpull-xpp3:3.0.0.20140325-SNAPSHOT не существует в указанных вами репозиториях.

Возможные причины:

• опечатка зависимость.
• Вы оставили репозиторий.
• Ваш локальный репозиторий Maven или кегель графа разбиты.

Рассмотрите возможность поиска дерева зависимостей, чтобы выяснить, откуда эта зависимость, и что делать, чтобы решить проблему.
