Note: there were 38 unkept descriptor classes in kept class members.
      You should consider explicitly keeping the mentioned classes
      (using '-keep').

Note: there were 13 unresolved dynamic references to classes or interfaces.
      You should check if you need to specify additional program jars.

Warning: there were 5 unresolved references to classes or interfaces.
         You may need to add missing library jars or update their versions.
         If your code works fine without the missing classes, you can suppress
