I have a script executed through the scriptler plugin and I would like to use in the script job environment variables such as BUILD_URL. At the beginnig of the script I read the environment variables with

def env = System.getenv() //also get the environment
//then print to confirm
env.each{
  println "${it.key} :${it.value}" 
}

Independent of whether I check the 'Propagate Job params to script' checkbox the parameters are the same and only related to the OS. I do not see any of the JOB related environement variables. See example screen shot attached
