我是混淆代码的新手。我正在使用Proguard来混淆一个大胖mycompanyrepo.jar文件（75MB）。我确实创建了一个proguard.cfg文件并放置了诸如-injar，-outjar，-libraryjars，-dontwarn，-ignorewarnings，-keep options等proguard选项，以确保构建成功。生成新的mycompany-obfuscated.jar。我将它部署在Vagrant VM中，并在使用功能时开始抛出下面的异常。基本上，它已经破碎了。我解压缩了mycompany-obfuscated.jar并查看了它内部以查看proguard对哪些类进行了模糊处理，看起来它几乎混淆了包括com.mycompany.mysrc包在内的每个lib jar。我试图解决以下异常，我不知道如何解决它。在爆炸的mycompany-obfuscated.jar中，我可以看到几乎所有的文件夹，并查看特定的类，如org.glassfish.jersey.internal.RuntimeDelegateImpl，它会抛出异常。
下面是proguard.cfg文件和异常详细信息。
