I am attempting to use a pipeline build triggered by github webhooks along with the kubernetes plugin.  I am seeing the following error in all of my poll logs:

[poll] Latest remote head revision on refs/heads/master is: f4065637e80be6789d6d16c59ceee2cfde7b7ba9 - already built by 5

ERROR: no such computer jenkins-slave-s10fr-lj69d

Done. Took 0.58 sec No changes

Looking at the plugin code there is a cache of what the workspace node has been in the past:

https://github.com/jenkinsci/workflow-api-plugin/blob/63e8ad0c271573f4bebc57fb0776b3fac4fccea9/src/main/java/org/jenkinsci/plugins/workflow/FilePathUtils.java#L115

Here is the line of code where the error is originating from:

https://github.com/jenkinsci/workflow-job-plugin/blob/01f9e9bf32452a9d2ed7fa1e0ef92303e991a0c6/src/main/java/org/jenkinsci/plugins/workflow/job/WorkflowJob.java#L593

Note that a workspace is required for the poll due to my use of "Additional Behaviors -> Polling ignores commits in certain paths"

Assuming that a computer is available is an invalid assumption in the cloud where nodes are ephemeral.   I haven't yet come up with a work-around for this issue, so I am currently blocked.

Thank you for your help!
