Is the associated PR (https://github.com/jenkinsci/xtrigger-lib/pull/7) dead in the water? The last activity was back on Sep 24, 2017.
We'd really, really like to be able to leverage the URL Trigger plugin from within pipeline code. At present, we're having to stick freestyle jobs that use URL Trigger (watching specific paths in our Artifactory instance) in front of pipeline jobs, but it's pretty clunky and does not scale well.
I'm not trying to be pushy - just trying to determine if we need to give up hoping for this issue (really
JENKINS-33691) to be resolved and start looking into other avenues.
