I am trying to run Proguard on my Android app and running into issues.

I am using SpongyCastle jar (copy and past of full bouncy castle with package renamed so it does not conflict with androids bouncy castle built in version)

When running proguard I see the following

How do I fix this? Add rt.jar to my libs?

The whole point of proguard is to shrink the code, but I keep adding jars to get around these issues where proguard complains it cannot find a class! Am I missing something?
