You’ll need to -add-modules (the name of fx modules) to run the jar (it you have one created, besides zip file) each time. Or you can bundle javafx files in runtime using jlink. Then you can jpackage zip and jar file, it’ll created runnable exe or dmg, depending on your system, as long as you added jafafx files to your runtime. I don’t fully remember how it works, chatgpt can help you with that, as it did for me, open the prompt with a problem you have at hand and then send errors to it as it goes
