An internal error occurred during launching testng in eclipse

Question

I have created the simple test class and getting error while executing it "An internal error occurred during: "Launching test". java.lang.NullPointerException".

I am fed up with this problem. I searched a lot on google and applied all the possible solutions but still getting same problem. I know, it is configuration problem but not able to figure out where?

Followed Steps to create the project:

• Open Eclipse
• Install TestNG Plugin
• Create Java Project
• Add TestNG Library
• Create TestNG Class
• Execute that class (as above)

Applied solution :

• Reinstalled the Eclipse.
• Reinstalled the TestNG Plugin
• Uninstalled the MVC TestNG plugin

Source Code:

package usermigration;

import org.testng.annotations.Test;

public class test {


@Test   
public void a()
{
    System.out.println("a");
}

}
