Compile JavaFx application in IntelliJ getResources() returns null

Question

When running the app inside IntelliJ, everything works fine.

When building artifacts, the reference to *.fxml files are not found and return when calling getClass().getResources("/path/to/fxml/file.fxml")

Executing *.jar or *.exe throws a NullPointerException: Location is not set.

How can this be resolved?

Answer 1

1. In IntelliJ, go to Project Structure -> Artifacts
2. In Output Layout Tab, click the + Icon and select Directory Content
3. Select your resource directory

If this doesnt work, inside your project in IntelliJ, right-click on your resource directory and select Mark Directory As.. -> Mark as Resource Root

Make sure your paths are in the following structure:

"/subdirectories/file.fxml"

So if your fxml-files are located at: resources/layout/main.fxml:

"/layout/main.fxml"

So / is your resource directory
