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

Question

I try start ProGuard on Spring Boot App And get error:

  [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]          you could try your luck using the '-ignorewarnings' option.
     [proguard] Error: Please correct the above warnings first.

Why I get this error and how can I fix it?

You could do the following to get rid of the situation:

If you add a proguard option -printconfiguration configuration.txt you will see all the proguard adds.

OR

You could use the following option to stop seeing these warning messages: Documentation here
