[JENKINS-9593] Copy artifact fails when slave is offline

Hello,

I have a matrix build which does some testing on several slaves.

At the end of this matrix job, a job is triggered in order to retrieve all logs and compile it in a global report.

I had to set a idle timeout for these slaves because I use the label-verifier plugin (which seems to dont have a category in Jenkins bugtracker).

And I want this verifier to check for the labels as often as possible (a slave can become unavailable and must be turned of in this case)

The problem is, a slave can shutdown because of the timeout (and not because of the label-verifier)

-> its workspace becomes unavailable to the report-job.

And then the report job fails with this message:

-> Unable to access workspace for artifact copy. Slave node offline?

It would be nice if the slave node could be restarted automatically when the artifact is needed.

PS:

Or/and if a "period" can be set on the label-verifier plugin

Sorry, I did not found the correct category to fill an "improvement request" on the label-verifier plugin too.

Start by reproducing the matrix-build report job when a slave shuts down and artifact copying reports "Unable to access workspace for artifact copy. Slave node offline?" Review the copyartifact-plugin and matrix-project-plugin entry points involved in workspace and artifact retrieval. Done means the intended offline-slave behavior is implemented and verified; the separate label-verifier period request remains an alternative mentioned in the issue.
