java.lang.IllegalStateException: Location is not set - at startup

Question

I want to run my application, but an exception returns to me. I found a similar question and did it the same way, but it did not help me. I think the mistake is stupid, but I don't see it, and I don't understand what to do, please help.

my main method

public class App extends Application {
    private Stage menuBar;
    private BorderPane mainWindow;

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage primaryStage) throws Exception {
        this.menuBar = primaryStage;

        initMenuWindow();
    }

    private void initMenuWindow() {
        try {
            FXMLLoader loader = new FXMLLoader();
            loader.setLocation(App.class.getResource("menuWindow.fxml"));
            mainWindow = loader.load();     //ERROR

            Scene scene = new Scene(mainWindow);
            menuBar.setScene(scene);

            menuBar.show();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

and exception

Exception running application zherikhov.App

my java module

module java {
    opens zherikhov to javafx.fxml;
    exports zherikhov;
    requires javafx.fxml;
    requires javafx.graphics;
    requires javafx.controls;
}

My guess is the path to the fxml file in loader.setLocation(App.class.getResource("menuWindow.fxml"));. Try "/menuWindow.fxml" and other options... See this question. — deHaar

@deHaar /menuWindow.fxml is probably the first thing I tried) and I also experimented with the paths, but I agree, I think the problem is somewhere here — Vlad Zherihov

This has been asked and answered dozens of times. Please try the search feature and search for "Location not set." — Zephyr

Then that's the source of the problem. Unfortunately, as you're using the IDE directly to build and run your project (rather than delegating to Maven), I'm not sure how to fix it. I would have assumed the problem was caused by IntelliJ not recognizing the src/main/resources directory as a resources root, but the directory's icon would indicate otherwise (you may want to still check this to be sure). If you run mvn compile are the resources copied? — Slaw

Your problem looks simple, Just replace the FXML file name menuWindow.fxml with the full path of the file starting at the src file, ending with the filename with the .fxml

I hope this works for you ( it worked in my case but your project's structure looks different)

I've probably tried all the different options for the paths, otherwise I would not have come here.
