When a maintenance window is started by Agent Maintenance plugin, Jenkins considers this as SCM change

    • Type: Bug
    • Resolution: Not A Defect
    • Priority: Minor
    • None
    • Environment:
      Windows Server installation of Jenkins LTS 2.426.3.
      Agent Maintenance plugin version 2.163.v08874cd79262

      When a maintenance window is started, Jenkins considers this as SCM change and all builds needlessly start and fill the build queue. After the maintenance window is over, all the build agents get busy performing builds, potentially causing builds triggered by real SCM changes to wait for several hours due to the queue.

      Example:
