getting nullpointer exception if running the testRun.java extends AbstractTestNGCucumberTests, by Ruuning it As 'TestNG Test'

Question

i am new TestNG. I am trying to integrate cucumber feature files with TestNG. And I am using a simple java project, not the maven. And for this, i wrote a simple code in my testRun.java

import org.testng.annotations.Test;
import cucumber.api.CucumberOptions;
import cucumber.api.testng.AbstractTestNGCucumberTests;


     @CucumberOptions(features = "src/features"
     ,glue = {"stepDefinitions"}
     )

     public class testRun extends AbstractTestNGCucumberTests{


     }

On right clicking, and run it as "TestNG Test", i am able to run the program, but getting a nullpointer exception with few other errors as below, Could someone please help me with this:

[RemoteTestNG] detected TestNG version 6.10.0

please update you cucumber jar to latest stable version and try again. It may resolve your problem. — Murthi, Jul 23 '18 at 07:14
Upgrade to latest testng version. What is the cucumber jar versions? — Grasshopper, Jul 23 '18 at 08:10
Facing same issue, please lets us know which dependency we have to use. — Girish, Sep 03 '20 at 12:48

There are multiple possibilities for the raised issue,

Check Runner class directory, Try to run and call Feature file and Step definition in same directory. so your CucumberOptions will be like:

@CucumberOptions(features = "features",glue = {"stepDefinitions"})

Else, Check your calling path for Step Definition and Feature file with reference to Runner class.

If its in Different directory, You path should be like :

@CucumberOptions(features = "./src/main/java/features", glue = {"stepDefinitions"})

"./" indicates current project workspace.
You can go for Step by step execution to Debug, where you are stuck
- Run with Runner class as TestNG Test
- Run with .XML file, as TestNg Suite
- Run with POM

So you will be have clear idea where you need to improve the things.
