How to tell Proguard to avoid obfuscating JNA library classes?

Question

In other words: what -keep commands should I use to tell Proguard to avoid obfuscating my classes that represent native libraries? (since JNA requires that the names match the equivalent native function, struct, etc.)

Answer 1

This is the rule I'm using for now:

-keepclassmembers class * extends com.sun.jna.** {
    <fields>;
    <methods>;
}

I still think there might be a better way to do it though.
