Minor This job is not a bug reported, it is intended to highlight the way that Jenkins processes shell environment variables and the impact that has on P4Jenkins variables:
In the example below 3 different syncs are perfromed on 3 nodes at 3 different times. Waits occur till the end of all sync's then P4_CHANGELIST is output from each of those nodes from a shell or command prompt.
Note how P4_CHANGELIST changes over time because different nodes sync at '@now' at different times but at the end all nodes report the same changelist ID which does not match the value they synced to.
$ grep "NODE_NAME|P4_CHANGELIST|syncing files at change" console.txt | grep -v syncID
