cucumber using java - Null pointer exception on executing tests from runner class

Question

i am getting null pointer execption when executing scenarios from runner class. when i execute from feature file then tests are executed without any error, I am using tags to run the scenarios and i have mentioned the tags in runner class, please let me know what might be the reason.

Runner Class Code:

@RunWith(Cucumber.class) 
@CucumberOptions( features={"Features"} ,glue={"project.stepdef"} ,tags = {"@chrome","@smoke"} , format = {"pretty", "html:target/site/cucuber-pretty","json:target/site/cucumber.json"} // ,monochrome = true ) 
public class CucumberRunner 
{ 

}

You need to make some minor tweaks to the runner Class as follows:

import org.junit.runner.RunWith;
import cucumber.api.junit.Cucumber;

@RunWith(Cucumber.class) 
@CucumberOptions( 
                    features="Features",
                    glue="stepdef",
                    tags = {"@chrome","@smoke"}, 
                    plugin = {"html:target/cucumber-html-report", 
                              "pretty:target/cucumber-pretty.text",
                              "json:target/cucumber.json"},
                ) 
public class CucumberRunner {}
