If using a project with user-defined axis, Jenkins doesn't trigger the given build node after checkout.

Here's a sample output (only the important parts), showing the correct checkout, after triggering axis failure (some names changed to xxx/yyy/uuu, the important parts bold):

Started by user uuu
Building remotely on WinMachine (windows) in workspace C:\Users\JenkinsSlave\workspace\xxx\yyy
[WS-CLEANUP] Deleting project workspace...
[WS-CLEANUP] Done
Checking out a fresh workspace because there's no workspace at C:\Users\JenkinsSlave\workspace\xxx\yyy
Cleaning local Directory .

Triggering xxx » yyy » TARGET=zzz
xxx » yyy » TARGET=zzzz completed with result FAILURE
Touchstone configurations resulted in FAILURE, so aborting...
Finished: FAILURE

A look at the detailed results from the axis build shows Jenkins isn't using the given build node (WinMachine) after checkout:

Started by upstream project "xxx/yyy" build number 14
originally caused by:
