Failed to load MXNet native library

[Lenkense]

Description

I'm trying to run TrainTicTacToe.java example. It used to work but for some reason is no longer working.

Expected Behavior

After running the main method of training should start.

Error Message

What have you tried to solve it?

I have found many solution involving gradle but I'm using maven so I don't know how to adapt thos solutions. Additionally many solutions link to README.md files that no longer exist.

java.lang.NoSuchMethodError, this is most likely you are using a mismatched DJL API and MXNet engine library.

You can use BOM to avoid versioning issue: https://docs.djl.ai/bom/index.html
