Hello everyone, I'm making a JavaFX application and I can't connect the library, what am I doing wrong?

Question

Java

These are the dependencies I added to pom


Here is the application launcher class
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

import java.io.IOException;

public class App extends Application {

private Stage primaryStage;

public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) throws IOException {
this.primaryStage = primaryStage;
showMainView();
}
private void showMainView() throws IOException {
FXMLLoader loader = new FXMLLoader();
loader.setLocation(getClass().getResource("resources/NewGame.fxml"));
Parent mainLayout = loader.load();
Scene scene = new Scene(mainLayout);
primaryStage.setScene(scene);
primaryStage.show();
}
}

Here is the JavaFX file


Here is the controller class
package controllers;

import java.io.IOException;
import java.net.URL;
import java.util.ResourceBundle;

import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;

public class NewGameController {

@FXML
private ResourceBundle resources;

@FXML
private URL location;

@FXML
private Button NewGameButton;

@FXML
private Button MainExit;

@FXML
void initialize() {
NewGameButton.setOnAction(new EventHandler() {
public void handle(ActionEvent event) {
NewGameButton.getScene().getWindow().hide();

FXMLLoader loader = new FXMLLoader();
loader.setLocation(NewGameController.this.getClass().getResource("/resources/SettingGame"));

try {
loader.load();
} catch (IOException e) {
e.printStackTrace();
}

Parent root = loader.getRoot();
Stagestage = new Stage();
stage.setScene(new Scene(root));
stage.showAndWait();
}
});
}
}

And these are the errors thrown by
