Some scene not loading after maven build

Question

I am developing JavaFx application in netbeans, in netbeans the project is building and running fine.

I made a build (mvn package) from my project its finished without error but when I launch the program its not loading all the scenes and the FXMLLoader return with null value in this cases.

All .fxml file in the same folder.

public class JavaFXApplication extends Application {

    public static final String TOOLBAR_MAIN = "toolbarMain";
    public static final String TOOLBAR_MAIN_FXML = "/fxml/ToolbarMain.fxml";
    public static final String TOOLBAR_SUB = "toolbarSub";
    public static final String TOOLBAR_SUB_FXML = "/fxml/ToolbarSub.fxml";

    public static final String NEW_SESSION_PANEL = "newSession";
    public static final String NEW_SESSION_PANEL_FXML = "/fxml/NewSessionPanel.fxml";
    public static final String OPEN_SESSION_PANEL = "openSession";
    public static final String OPEN_SESSION_PANEL_FXML = "/fxml/OpenSessionPanel.fxml";
    public static final String CONNECTIONS_PANEL = "connections";
    public static final String CONNECTIONS_PANEL_FXML = "/fxml/ConnectionsPanel.fxml";
    public static final String LOGS_PANEL = "logs";
    public static final String LOGS_PANEL_FXML = "/fxml/LogsPanel.fxml";
    public static final String EXCEPTIONS_PANEL = "exceptions";
    public static final String EXCEPTIONS_PANEL_FXML = "/fxml/ExceptionsPanel.fxml";
    public static final String MESSAGES_PANEL = "messages";
    public static final String MESSAGES_PANEL_FXML = "/fxml/MessagesPanel.fxml";

    public static ScreensController menuContainer = new ScreensController();
    public static ScreensController contentContainer = new ScreensController();

    public static ServerService server = new ServerService();

    public static Stage STAGE;

    @Override
    public void start(Stage primaryStage) throws Exception {

        STAGE = primaryStage;

        primaryStage.setOnCloseRequest((WindowEvent t) -> {
            if (server.isRunning()) {
                server.cancel();
            }
        });

        menuContainer.loadScreen(JavaFXApplication.TOOLBAR_MAIN,
                JavaFXApplication.TOOLBAR_MAIN_FXML);
        menuContainer.loadScreen(JavaFXApplication.TOOLBAR_SUB,
                JavaFXApplication.TOOLBAR_SUB_FXML);

        contentContainer.loadScreen(JavaFXApplication.NEW_SESSION_PANEL,
                JavaFXApplication.NEW_SESSION_PANEL_FXML);
        contentContainer.loadScreen(JavaFXApplication.OPEN_SESSION_PANEL,
                JavaFXApplication.OPEN_SESSION_PANEL_FXML);
        contentContainer.loadScreen(JavaFXApplication.NEW_SESSION_PANEL,
                JavaFXApplication.NEW_SESSION_PANEL_FXML);
        contentContainer.loadScreen(JavaFXApplication.CONNECTIONS_PANEL,
                JavaFXApplication.CONNECTIONS_PANEL_FXML);
        contentContainer.loadScreen(JavaFXApplication.LOGS_PANEL,
                JavaFXApplication.LOGS_PANEL_FXML);
        contentContainer.loadScreen(JavaFXApplication.EXCEPTIONS_PANEL,
                JavaFXApplication.EXCEPTIONS_PANEL_FXML);
        contentContainer.loadScreen(JavaFXApplication.MESSAGES_PANEL,
                JavaFXApplication.MESSAGES_PANEL_FXML);
        menuContainer.setScreen(JavaFXApplication.TOOLBAR_MAIN);
        contentContainer.setScreen(JavaFXApplication.NEW_SESSION_PANEL);

        SplitPane root = new SplitPane();

        root.getItems().addAll(menuContainer, contentContainer);
        Scene scene = new Scene(root);
        primaryStage.setScene(scene);
        primaryStage.show();
        primaryStage.setResizable(false);
        primaryStage.setTitle("Exam Supervisor");

    }

Screen controller where the screens loaded:

public class ScreensController extends StackPane {

    private HashMap<String, Node> screens = new HashMap<>();

    public void addScreen(String name, Node screen) {
        screens.put(name, screen);
    }

    public boolean loadScreen(String name, String resource) {
        try {
            FXMLLoader myLoader = new FXMLLoader(getClass().getResource(resource));
            System.out.println("name:" + name + " ,resource" + resource + " ,loader:" + myLoader.getLocation());
            Parent loadScreen = myLoader.load();
            ControlledScreen myScreenControler
                    = myLoader.getController();
            myScreenControler.setScreenParent(this);
            addScreen(name, loadScreen);
            return true;
        } catch (Exception e) {
            System.out.println("name: " + name + ", resource" + resource + " ,exception: " + e.getMessage());
            return false;
        }
    }

    public boolean setScreen(final String name) {

        if (screens.get(name) != null) {
            final DoubleProperty opacity = opacityProperty();

            if (!getChildren().isEmpty()) {
                getChildren().remove(0);
                getChildren().add(0, screens.get(name));
            } else {
                getChildren().add(screens.get(name));
            }
            return true;
        } else {
            System.out.println(screens.get(name) + " ,screen hasn't been loaded!\n");
            return false;
        }

    }

    public boolean unloadScreen(String name) {
        if (screens.remove(name) == null) {
            System.out.println("Screen didn't exist");
            return false;
        } else {
            return true;
        }
    }
}

Answer 1

I looked into your netbeans project files and the maven pom and found nothing strange. The fact that the javafx libs are not contained in the classpath of both configurations tells me that, you are using it from the Java Installation.

Perhaps you use a differrent Java installation from netbeans and when you start the maven target. Then, the fxml module might be missing or there is no java fx installed with the second installation or something else is not compatible.

Did you start the maven target from a console? e.g.

java -jar xyz.jar

Try

java -version

and compare the version with the java version used by netbeans (Help > About).

Netbeans build are done by an internal maven version. But there is also a chance that an external maven build uses a different version of the java compiler than the internal netbeans build.

I hope that helps!

Try to use javafx-maven-plugin Hope, it can help.
