Сборка проекта с javafx

После сборки проекта, как через стандартные средства ide (intellij idea), так и с помощью сборщика Maven, после запуска джарника все в порядке, пока не наступает момент переключения окна. Возникает ошибка:

Exception in thread "JavaFX Application Thread" java.lang.IllegalStateException: Location is not set.

Если требуется какая-то дополнительная информация скажите, что необходимо прислать?

Дополнительная информация:

Место установки в классе LogInController:

public class LogInController {
    @FXML
    private TextField user;
    @FXML
    private PasswordField password;
    @FXML
    private Label errorPass;
    @FXML
    private Button logInButton;
    @FXML
    public void initialize(){
        password.setText("1");
        user.setText("1");
        KeyCodeCombination kComb = new KeyCodeCombination(KeyCode.ENTER, KeyCombination.SHIFT_DOWN);
        logInButton.setOnKeyPressed(new EventHandler<KeyEvent>() {
            @Override
            public void handle(KeyEvent keyEvent) {
                if (keyEvent.getCode() == KeyCode.ENTER)  {
                    logInButton();
                }
            }
        });
    }

    @FXML
    public void logInButton() {
        User.getUserRole(user.getText(), password.getText());
        if (User.USER != null) {
            Stage stage = (Stage) user.getScene().getWindow();
            stage.close();
            try {
                FXMLLoader loader =  new FXMLLoader(getClass().getResource("../View/MainMenu.fxml"));
                loader.setController(new MainMenuController());
                Parent pane = loader.load();
                Stage primaryStage = new Stage();
                Scene scene = new Scene(pane);
                primaryStage.setScene(scene);
                primaryStage.show();
                primaryStage.setMinHeight(640);
                primaryStage.setMinWidth(920);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }else{
            errorPass.setVisible(true);
        }
    }
}
