Getting errors during my first application using javafx

Question

So I just started with javafx and it's giving me a error which is simply not getting resolved. This is the main class code . I have no clue why this is happening.

package loginapp;

import com.sun.tools.javac.Main;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class LoginApp extends Application {
    public void start(Stage stage)throws Exception
    {
        Parent root=(Parent) FXMLLoader.load(getClass().getResource("login.fxml"));
        Scene scene=new Scene(root);
        stage.setScene(scene);
        stage.setTitle("Equipment Management System");
        stage.show();
    }
    public static void main(String[] args)
    {
        launch(args);
    }

}

This is the fxml file text:

?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.layout.*?>


<AnchorPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="-Infinity" minWidth="-Infinity" prefHeight="400.0" prefWidth="500.0" xmlns="http://javafx.com/javafx/11.0.1" xmlns:fx="http://javafx.com/fxml/1" />

I haven't written any code in the controller yet !

THIS IS THE ERROR MESSAGE
