Hello
I had some issues when I wanted load materialfx.jar and others .jar:

I believe that I have successfully loaded the JAR files in build.rs, although it's possible that I have guided badly with the documentation.
It's my build.rs:

let root = "/home/cube/Documentos/delete/vscode/github/pyramo";

}Hi 👋
I was having issues running my own j4rs project so I thought I'd try your showcase.
cargo run runs fine but when selecting an option of f or n I get the following error:
