How to set paths on JavaFX for a local project

Question

I want to make a local JavaFX application but I don't know how to set the paths to the files so when I build the jar I won't have any problem.

I've built the jar and tried to fix as many errors as I could but I'm still having some that I can't fix.

Here is a pic of the source folder.

These are the errors I have

This is the 21st line at Main Parent home = FXMLLoader.load(getClass().getResource("home.fxml"));

Your error log says Caused by: java.lang.ClassNotFoundException: com.jfoenix.controls.JFXButton. This means the fxml could not get loaded because the class JFXButton could not been found. I think there is a problem with your library imports of jfoenix or you forgot to include the JFXButton import in your FXML file.

*"or you forgot to include the JFXButton import in your FXML file"* How would `FXMLLoader` come up with the correct fully qualified class name in this case??? – fabian Jul 15 '17 at 07:40
Good point. I was just thinking of stuff I would check in this case. – Nash Jul 15 '17 at 07:59
