Groovy, Selenium, Cucumber, adding ChromeOptions arguments - selenium

Question

I wanted to create a BaseTest.groovy where i implement the Webdriver with headless mode.
package api
import org.openqa.selenium.WebDriver
import org.openqa.selenium.chrome.ChromeDriver
import org.openqa.selenium.chrome.ChromeOptions
class BaseTest{
ChromeOptions chromeOptions = new ChromeOptions()
chromeOptions.addArguments(["--headless", "--no-sandbox"])
static WebDriver driver = new ChromeDriver(chromeOptions)
}
I have a LoginSteps.groovy stepdefinitions file
package stepDefinitions
import api.Helper.helper
import org.openqa.selenium.WebDriver
import org.openqa.selenium.chrome.ChromeDriver
import org.openqa.selenium.chrome.ChromeOptions
import static cucumber.api.groovy.EN.*
Given(~/^I am on the xyz login page$/) { ->
helper.setPage("https://xyzTestpage.com/")
}
When(~/^I sign in as "([^"]*)"$/) { String arg1 ->
helper.signIn("username","password")
}
Then(~/^I load the homepage$/) { ->
helper.setPreset()
}
And i have a helper.groovy file where i implement the methods
package api.Helper
import api.BaseTest
import api.Xpaths.LoginPageXpaths
import api.Tools.tools
import org.openqa.selenium.By
import org.openqa.selenium.WebElement
class helper extends BaseTest {
static void setPage(String url){
driver.get(url)
}
static void signIn(String username, String password){
WebElement uname = driver.findElement(By.xpath(LoginPageXpaths.userNameField()))
uname.sendKeys(username)
WebElement pwd = driver.findElement(By.xpath(LoginPageXpaths.passWordField()))
pwd.sendKeys(password)
WebElement loginButton = driver.findElement(By.xpath(LoginPageXpaths.loginButton()))
loginButton.click()
}
static void setPreset(){
WebElement multiCountry = driver.findElement(By.xpath(LoginPageXpaths.multiCountryButton()))
multiCountry.click()
WebElement openButton = driver.findElement(By.xpath(LoginPageXpaths.openButton()))
openButton.click()
String inputWindow = driver.getWindowHandle()
for(String loggedInWindow : driver.getWindowHandles()){
driver.switchTo().window(loggedInWindow)
}
WebElement lineItem = driver.findElement(By.xpath(LoginPageXpaths.calculateButtonXpath()))
tools.waitForElementToBeClickable(driver,lineItem,25)
driver.quit()
}
}
So my problem is, i don't know where should i set the headless mode, because i got error, when i run this.

Answer 1

Can you please try adding arguments separately as below and run it
class BaseTest{
ChromeOptions chromeOptions = new ChromeOptions()
chromeOptions.addArguments("--headless");
chromeOptions.addArguments("--no-sandbox");
static WebDriver driver = new ChromeDriver(chromeOptions)
}
