Maven, как описать зависимость от fxml?

public class Main extends Application {
 
    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sam.fxml"));
        primaryStage.setTitle("Hello World");
        primaryStage.setScene(new Scene(root, 600, 400));
        primaryStage.show();
    }
 
    //  ant -f D:\stadyIdea\ANT\build.xml
 
    public static void main(String[] args) {
        launch(args);
    }
