No I have not tried to build Maud on my computer. My point is that Gradle absolutely does not do anything magic to control the order the JVM finds classes because it can’t.
The reason it can’t is as Paul says. Classloading is machine dependant. In practice you might predict the order (like specifying manifest attributes) but in theory there are no guarantees since classloaders are allowed to do parallel loading.
So maybe that is the difference you experience? The ant and gradle builds maybe sets up the manfest attribute differently?
Just re-reading this post. Is there any possibility of seeing the ant file that you are using?
Looking-down-the-straw from a distance, it sounds like somehow the fileset that copies libraries from dist/lib to the various platform distributions is being set up in a way that excludes or filters the Minie jar, perhaps based on some peculiarity with it’s name?

That’s the most sensible suggestion I’ve heard so far. The XML files are unchanged from JME’s BasicGameTemplate, which can be found at https://github.com/jMonkeyEngine/sdk/tree/v3.2.2-stable-sdk1/BasicGameTemplate

Right here. the property deployment.jarexcludes is set in calls to the classes
com.jme3.system.ExtractNativeLibraries &com.jme3.system.NativeLibraryLoader.
Essentially, this entire build system assumes that Native libraries have two components:
An ‘API’ jar, which has all of the JNI *.class files, as well as any ‘ergonomics’ wrapper over them, e.g. jme3-bullet
A ‘native package’ jar, which includes the actual native libraries, including any JNI callback stubs, e.g. jme3-bullet-native
The ant task copies all native libraries to ${build.dir}/natives/$PLATFORM during the earlier build steps, and then excludes the .jar file from the deployment list during this step.
Your work-around works because the A1 jar is not listed in the places that check for native libraries. It’s therefore ignored, and just copied blindly with the rest of the /lib/*
I’m not sure if this assumption should be treated as a bug, or a (poorly documented) feature. If it’s a bug, there needs to be code to remove the native files from the jar before it is copied to the deployment location, to avoid wasted distribution bandwidth.

Thank you @sailsman63 for digging into this.
In order to conform to the expectations/assumptions of desktop deployment, I could split the Minie library into multiple JARs. My only reluctance is because it would introduce yet another opportunity for version mismatches between JARs.
