UnsatisfiedLinkError when using proguard

[Goooler]

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?

[ajalt]

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