FXML load exception

I had a problem that I absolutely can not solve on my own, because I just started using JAVA FX. I get the nasty javafx.fxml.LoadException: but I did exactly as a guide, but I can not start my Main. This is the exception output:

The problem is in the source.

So you have to change it to the correct one

So do it, edit the fxml file source here

 AnchorPane root = (AnchorPane) FXMLLoader.load(Main.class.getResource("LoginGUI.fxml"));

with this

 AnchorPane root = (AnchorPane) FXMLLoader.load(Main.class.getResource("/packagename/LoginGUI.fxml"));

I also had this problem. I found that I did not add the package name to the controller name specified in the FXML file; At first, I just added the controller class name. For example: if my controller class is under com.stackoverflow.gui package and my controller class name is LoginController . The FXML file must have com.stackoverflow.gui.LoginController , not just LoginController
