Sikuli Example?

I’m using the default built in libraries, I got as far as:

import org.sikuli.api.Screen
import org.sikuli.core.search.Match

@Keyword
def findImage (String image) {

  Screen s = new Screen()
  Match match = s.find(image)
  println('***********************' + match)

}

but it won’t let me create an instance of Screen and complains, does anybody have working code example, want to find an image inside a region.

I also can’t import pattern not sure if it’s needed.

Thanks
