【问题描述】：

我试图混淆我打包到 SINGEL jar 中的 java 应用程序。该应用程序使用 SWT gui 库等。我已经通过 -libraryjars 在 Proguard 配置文件中正式列出了它们，但我仍然收到太多相同类型的警告，即： "警告：库类 org.eclipse.swt.accessibility.Accessible$10 扩展或实现程序类 org.eclipse.swt.internal.ole.win32.COMObject"

这里做错了什么？？

这是我的 Proguard 配置的样子：

【参考方案1】：

ProGuard manual > Troubleshooting > Warning: library class ... depends on program class ...

在这种情况下，org.eclipse.swt.internal.ole.win32.COMObject 似乎在您的输入 jar fevflex.jar 中。您应该将其删除，或者至少将其作为库 jar 的一部分。

【参考方案2】：

我注意到您在库中同时包含 swt.jar 和 swt_64bit.jar，而一次只能使用其中一个。也许这是您收到大量警告的原因之一。
