Create executable box for selenium code

I need to create an executable Jar file for Selenium Webdriver Project (TestNG) using Eclipse.

After traversing various websites, I realize that we need to create a main class to execute the test suite.

I created a Main class with the code below.

package com.testcases;
import java.util.ArrayList;
import java.util.List;
import org.testng.TestListenerAdapter;
import org.testng.TestNG;
import org.testng.xml.XmlClass;
import org.testng.xml.XmlSuite;
import org.testng.xml.XmlTest;

public class Main {
public static void main(String[] args) {
    // TODO Auto-generated method stub
    TestListenerAdapter tla = new TestListenerAdapter();
    TestNG testng = new TestNG();
     Class[] classes = new Class[]{
             Abc.class,
             PQR.class,
             XYZ.class
             };
     testng.setTestClasses(classes);
     testng.addListener(tla);
     testng.run();
    }
}

      

        
        
        
      

    

When I created the runnable Jar using Export-> Java-> Runnable Jar from Selenium and after running the jar file using the command line with the following command:

java -jar AbcXyz.jar

      

        
        
        
      

    

Program execution ends up in an infinite loop

Help build such an executable Jar file.
