I am trying to use AShot with Selenium to take a screenshot.
require 'selenium/webdriver'
require 'javalib/ashot-1.5.4.jar'
driver_path = 'C:\ProgramData\chocolatey\lib\chromedriver\tools\chromedriver.exe'
Selenium::WebDriver::Chrome::Service.driver_path = driver_path
base_url = 'https://www.google.com/'
driver = Selenium::WebDriver.for :chrome
driver.navigate.to base_url
ashot = Java::RuYandexQatoolsAshot::AShot.new
png = ashot.takeScreenshot(driver)
test_pod_name = 'c:\data\google_screenshot.png'
File.write(test_pod_name, png)
puts "Writing to: #{test_pod_name}"
driver.close
But I am getting this error message:

It's funny that the error dump doesn't refer to AShot - but the error originates from the line instatiating AShot.
There is an open method in Selenium-webdriver method for capturing screenshots. You can use something like
