We use a Perforce Trigger that calls curl to POST to the /p4/change endpoint exposed by the p4-plugin. With 1.10.6, this trigger worked, and the relevant job would run. Upgrading to 1.10.10, and the trigger stopped working.
In investigating the issue, 1.10.10 was still logging "doChange: Received trigger event for: <p4port here>", but the usual followup log "probeJobs: P4: probing: <jenkins job>" never appeared. Rolling the plugin back to 1.10.6 restored the ability to trigger the jenkins job.
