Can you please add an option to promotion configuration for a triggering build to wait its promotion to complete and fail if promotion fails?
I have a use case where Level 1 build triggers Level 2 build, but only Level 1 build artifacts get checked out by Level 3 build. I use build triggering and build.transferFiles() to transfer files from still running Level 1 build to a triggered Level 2 build. I don't like that as it doesn't propagate the list of changes and authors. I can't use promotion as I need Level 1 to complete only when Level 2 completes so that Level 3 can check it out. I can't make Level 1 to wait for its promotions to complete as they don't start until the build is complete.
