Я пытаюсь запутать свой Java-проект Libgdx с помощью ProGuard, но в какой-то момент я получаю сообщение об ошибке Themeable Widget Library в какой-то момент. Это для моего проекта Desktop (не Android):
Ignoring unused library classes...
Original number of library classes: 19830
Final number of library classes: 880
Optimizing...

Я не понимаю выброшенное исключение. Я пропустил, чтобы включить библиотечную банку? Когда я удаляю строку «dontwarn de.matthiasmann.**» из моей конфигурации proguard, я получаю такие ошибки, как «не могу найти ссылочный класс de.matthiasmann.twl.Widget». Я прямо указываю ProGuard сохранять классы из libgdx и matthiasmann (библиотека виджетов: http://twl.l33tlabs.org/), чтобы они не были запутаны (в любом случае они с открытым исходным кодом).
