Java ProGuard can't find referenced class

Question

I'm trying to obfuscate my java code with ProGuard (as suggested on stackoverflow).

However I'm getting "cant find referenced class" errors

Below is my configuration, I didn't change anything from default really. Just added input and output jars.

I've searched on the internet for solutions for a while and many suggested -ignorewarnings or -keepclass ..... But none of them seem to work.

Hopefully someone can help me :) I prefer using the GUI if possible.

The Java8 runtime references some additional classes that are not present in rt.jar but in plugin.jar. It is safe to ignore these warnings, so you can specify the following option in your configuration:

-dontwarn netscape.javascript.*
