How do you implement the jenetics/jpx library

please reference GitHub - jenetics/jpx: JPX - Java GPX library
I have this library downloaded onto my machine. It will build in Android Studio via the terminal window. Yet I can’t seem to point to it, either via dependency designation nor classpath, etc. in the project level build.gradle. I’ve followed a couple of recommendations off the web but still no luck.
I just want to get this library to be available in another A.S. project where I can then implement the various utilities to generate GPX files. I even generated a module within my project that should be “adding” this library. Still no luck.
The current error when syncing w/ gradle is primarily “Unresolved reference: JPX”.
Any input would be much appreciated.
