I'm using clikt in Diffuse with ProGuard minify enabled, output:

./diffuse diff --jar diffuse-0.2.0-SNAPSHOT-java11.jar diffuse-0.2.0-SNAPSHOT-java16.jar
Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't obtain static method dispose from class com.sun.jna.Native

Workaround is to add keep rules in config:

# https://github.com/java-native-access/jna/issues/1187#issuecomment-626251894
-keep class com.sun.jna.** { *; }
-keep class * implements com.sun.jna.** { *; }

I'm wondering if we can add rules into https://github.com/ajalt/mordant/blob/master/mordant/src/jvmMain/resources/META-INF/native-image/com/github/ajalt/mordant/reflect-config.json?

That file is for graal, I don't think proguard looks at it.

This isn't really a bug in mordant, but we could potentially mention those rules in the docs for the people who use proguard.

Or just bundle the rules file under resource folder?

If that works, I'd rather do that since the rules are short.
