How to call Java main method from Groovy Script in SoapUI

avidCoder, I do not have any method in the class. It's the only main method I have in the class. I try doing this but it did not work

My java code looks like this

package project;

public class MyClass{

public static void main(String[] args) {
// performing some functionality here
}

}

Groovy script :

import project.MyClass;

MyClass sample = new MyClass();
sample.main(".abcd","Test","tom","pass"); 

It throws below error and I am not sure, Is this error coming because I am calling main method or any other issue

ERROR:java.lang.NoSuchMethodError: com.google.common.util.concurrent.SimpleTimeLimiter.create(Ljava/util/concurrent/ExecutorService;)Lcom/google/common/util/concurrent/SimpleTimeLimiter;
