I've been working on Groovy code to do this. Essentially it takes the
slave "offline" (equivalent to clicking "Mark this node temporarily
offline" button). Any running jobs on the slave continue, but no new
jobs are accepted. Once the slave is offline it goes into a loop
monitoring the countBusy() method on the slave's computer object. When
the value gets down to 1 (the currently running shutdown job) it is safe
to go ahead and reboot.
I started with code from
https://bugreports.qt-project.org/browse/QTQAINFRA-558, and added the
loop to monitor busy executors. Also, you will need to bring the slave
back online after it reboots, because it will remember it was taken
offline. I used the code from
https://wiki.jenkins-ci.org/display/JENKINS/Monitor+and+Restart+Offline+Slaves
.

I'm searching for a more robust way of rebooting a Windows slave. I
reboot our windows slaves every night as I find that they tend to play
up if left too long without a restart.
Currently I try to a block builds plugin to block jobs so that the
slave can be rebooted, however from time to time a job will fail
because it got triggered in the narrow window between the reboot being
triggered and the slave shutting down, or if the slave is particularly
busy it might be hours before the reboot job can get started.
I've wondered about giving up on the blocking mechanism and create a
job that would run on the Slave, using Jenkins CLI to take the node
offline, wait for any currently running jobs (except for itself) to
complete, and then reboot the slave - I am assuming the node would
automatically come back online.
1. Is this a sensible idea?
2. If so - how do I check if any jobs are running on a node?
3. Anyone have a better idea?
