  21. # For triggering jobs jenkins cli is sufficient: https://support.cloudbees.com/hc/en-us/articles/228392127-How-to-wait-for-build-to-finish-when-triggering-from-CLI-
  22. #
  23. # The script is dependent on the current jenkins implementation of:
  24. # - the promotion web page (links for triggering/re-executing the promotions)
  25. # - the behaviour of the XML of the promotion status
  26. #
  27. # The behaviour of the job run status XML is:
  28. # - if the the promotion is not yet been triggered than the response is 404 not found
  29. # - is the the promotion has been triggered
  30. # - ... but it's still waiting for an executor: the response is 404 not found or <duration> is empty
  31. # - ... and has started: <duration> is empty or 0
  32. # - ... and it's finished: <duration> is a non-zero number
  33. #
  34. #
  35. # run syntax:
  36. # ./trigger_promotion_and_wait_for_completion.sh
  37. # <job_name>
  38. # <job_run_number_to_promote>
