Hi everyone:
I’m running a Jenkins server on a Mac mini and have been using scheduled (cron-based) builds. Everything worked fine initially, but after about two weeks, I started encountering an unusual issue involving duplicate and inconsistent builds.
Here’s the setup:
Job A is configured with a periodic (scheduled) build trigger.
Job B is set up as a downstream job that is triggered by Job A (i.e., Job A is its upstream project).
At first, both jobs ran as expected. However, roughly two weeks later, some previously successful builds of Job B were unexpectedly re-triggered—using the exact same build parameters and Git branch as they had two weeks prior.
For example (as shown in the attached screenshot):
Build #2596 of Job B was triggered by build #2791 of Job A.
But build #2791 of Job A was completed weeks ago, not recently.
Strangely, this problematic build (#2596) does not appear in the standard build history list on Job B’s main page. I can only access it by manually entering the build number in the URL (e.g., /job/JobB/2596/).
Despite being hidden from the UI, the build artifacts for #2596 do exist, and their timestamps match what’s shown on the build page.
This behavior is very puzzling. Has anyone else experienced something similar?
Additional context:
The Mac mini has been running continuously for several months without issues—only Jenkins exhibits this problem.
Last week, I disabled the scheduled trigger on Job A entirely. As expected, no new scheduled builds occurred.
However, even after disabling the trigger, old builds from two weeks ago are still somehow re-triggering Job B, again using outdated parameters and Git states.
Any insights or suggestions would be greatly appreciated!
Thanks in advance!
