我想用ProGuard對我的Libgdx Java項目進行混淆，但是在某些時候我在某些時候出現了關於Themeable Widget庫的錯誤。這是我的桌面項目（非安卓）：Libgdx和ProGuard不能與Themable Widget庫（桌面）一起工作

我不明白拋出的異常。我錯過了包括一個圖書館罐子嗎？當我從我的proguard配置中刪除'dontwarn de.matthiasmann。**'這一行時，出現「無法找到引用的類de.matthiasmann.twl.Widget」等錯誤。我明確告訴ProGuard從libgdx和matthiasmann（The Widget Library：http://twl.l33tlabs.org/）開始保留類，以便它們不會被混淆（它們無論如何都是開源的）。
