在JavaFX应用程序上运行proguard后，我收到以下错误。如果不使用proguard，则应用程序可以正常运行。我搜索了StackOverflow并找到了一些帖子，但是尝试各种答案都没有成功。Exception in thread "JavaFX Application Thread" Exception in thread "main" java.

变通
如果将以下内容添加到proguard配置中，我可以解决该问题并使它运行。
-dontoptimize
我想我确实想优化，但是似乎并没有对它进行太多混淆。我如何解决这个问题，但是要尽我所能去做得最好呢？
最佳答案
好吧，如果有人偶然发现这个问题并遇到类似的问题，我已经通过在运行它之前将jar文件不移到另一个位置来修复了我的问题。我收到了NoClassDefFoundError错误，因为尝试使用的类位于libs文件夹中，在我移动.jar（而不是libs文件夹）后无法访问这些文件夹。一个很容易解决的问题，但是在StackOverflow上找到了很多不同的建议，我没想到现在似乎变得如此显而易见。
关于java - 在JavaFX应用程序上运行Proguard后出现NoClassDefFoundError，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/36290192/
