proguard 注意：库类的重复定义

Question

我尝试在 Spring Boot App 上启动 ProGuard 并得到错误：

  [proguard] Reading library jar [C:\Program Files\Java\jdk1.8.0_151\jre\lib\rt.jar]

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

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

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

     [proguard] Note: duplicate definition of library class [javax.annotation.Resource$AuthenticationType]

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

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

     [proguard] Note: there were 8 duplicate class definitions.

     [proguard]       (http://proguard.sourceforge.net/manual/troubleshooting.html#duplicateclass)

     [proguard] Warning: there were 2 classes in incorrectly named files.

     [proguard]          You should make sure all file names correspond to their class names.

     [proguard]          The directory hierarchies must correspond to the package hierarchies.

     [proguard]          (http://proguard.sourceforge.net/manual/troubleshooting.html#unexpectedclass)

     [proguard]          If you don't mind the mentioned classes not being written out,

     [proguard]          you could try your luck using the '-ignorewarnings' option.

     [proguard] Error: Please correct the above warnings first.

为什么我会收到这个错误，我该如何解决？
