用Proguard插件混淆java jar

Question

我不知道如何使用Proguard插件来混淆Java jar

这是我正在使用的配置

<plugin>

        <options>                                                     
                                                                      
        </options>                                                    
        <libs>                                                        
            <lib>${java.home}/lib/rt.jar</lib>                        
            <lib>${java.home}/lib/jce.jar</lib>                       
        </libs>

我得到了几条像这样的线

 [proguard] Warning: class [BOOT-INF/classes/com/torchai/service/textextractor/aspect/ControllerLayerAspect.class] unexpectedly contains class [com.torchai.service.textextractor.aspect.ControllerLayerAspect]

甚至更像这样

 [proguard] Note: duplicate definition of library class [javax.annotation.ManagedBean]

为什么它告诉我我有重复的课程？为什么它会抱怨文件的名称似乎正确
