Jenkins 1.456 with Perforce Plugin 1.3.10 on both Windows and Linux. Cannot seem to invoke the p4 client (it is in the path). Seeing the exception:

Could not run perforce command. Finished: FAILURE Notice 'cannot run program ""' On the wiki screenshots there appears to be a way to set the path to your p4 client which I am not seeing. Also clicking 'Advanced' P4 Executable shows an empty read-only dropdown box.
