Problem with Jar file loading in Scene Builder

Question

I have a problem with adding my jar file to the Scene Builder Library. When I click open, nothing shows in the import dialog.

private Alert mb;
public FXMLDocumentController() {
        FXMLLoader fxmlLoader = new FXMLLoader(
        getClass().getResource("/data/Data.fxml"));

        fxmlLoader.setRoot(this);
        fxmlLoader.setController(this);

        try {
            fxmlLoader.load();
        } catch (IOException exception) {
            throw new RuntimeException(exception);
        }
        mb = new Alert(Alert.AlertType.CONFIRMATION);
    }

What I have found out so far is that when I comment "mb = new Alert(Alert.AlertType.CONFIRMATION);"the problem disappears and the jar loads.

How is the alert affecting all this?

Javafx sdk 11, Java jdk 11, Scene Builder 11

Answer 1

Have you tried to add the alert before fmxlLoader.load() and see if that works
