Can't run the Java project in NetBeans

Question

When I try to run my java project in NetBeans with a Scanner in it, it doesn't run and shows error message in the output field. "FAILURE: Build failed with an exception.(Scanner). processResources NO-SOURCE".

When I delete names[x] = s.next(); and grades[x] = s.nextInt(); it runs. I looked for a solution a lot but non of them have worked for me. Note that I can run the same code in Android Studio. I'm a beginner in programming, anyone have an idea how to fix it??

My code:

package codePracticing;
public class Main {
    public static void main(String args[]) {
        
        
        java.util.Scanner s = new java.util.Scanner(System.in);
        
        String names[] = new String[5];
        int grades[] = new int[5];
        
        for (int x = 0; x < names.length; x++){
            if (x != 3){
                System.out.println("Enter Name Of Student Number" + String.valueOf(x + 1) + ": ");
                names[x] = s.next();
                System.out.println("Enter Grade Of Student Number" + String.valueOf(x + 1) + ": ");
                grades[x] = s.nextInt();
            }
        }

        for (int x = 0; x < names.length; x++){
            if (x != 3){
                System.out.println("Student Number " + String.valueOf(x + 1) + " " + names[x] + " ; Grade: " + grades[x]);
            }
        }

The error message in the Output tab:

JAVA_HOME="C:\Program Files\Java\jdk-16.0.2"
cd C:\Users\***\Documents\NetBeansProjects\codePracticing; .\gradlew.bat --configure-on-demand -x check run

I tried to copy the code to a "Java with Ant" project (instead of "Java with Gradle") and it worked without problems.

File → New project → Java with Ant → Java Application

So what is "Ant" and "Gradle", what's the difference between them & why can't I use the "Scanner" methods in the Gradle? – The Maestro Sep 14 '21 at 15:01

There is no problem in this code if you run it on java/ant. but if you want to run it on gradle you should see this post. java.util.scanner throws NoSuchElementException when application is started with gradle run
