I'm working on a JavaFX project using NetBeans, and I've encountered an issue with loading an FXML file. Originally, my VentanaLogin.fxml file was in the practica6.main package, but I moved it to a new package practica6.vista to better organize the project.

Exception running application practica6.main.main
C:\Users\Usuario\Documents\NetBeansProjects\Practica6_Parte3\nbproject\build-impl.xml:1367: The following error occurred while executing this line:
C:\Users\Usuario\Documents\NetBeansProjects\Practica6_Parte3\nbproject\build-impl.xml:962: Java returned: 1
BUILD FAILED (total time: 2 seconds)
The FXML file is located at src/practica6/vista/VentanaLogin.fxml.
In my Main class, I load the FXML like this:
FXMLLoader.load(getClass().getResource("/practica6/vista/VentanaLogin.fxml"));
This is the general structure on my packages
However, the program still fails to load the FXML file. I have tried cleaning and rebuilding the project, but the issue persists. Does anyone know what could be causing this error or what I may have missed when moving the FXML file to a new package?
srcfolder, it should be together with all the compiled Java classes, i.e. files with the.classextension. I don't use NetBeans, I use Eclipse and as part of the build process (not Maven), Eclipse copies resource folders to the build destination folder.fx:controller="...". So, basically, you want to paste your old FXML code, but make sure you replace the oldfx:controller="..."with the newly created one.
