I've created a perforce workspace and I've sync it to the head version.

However I would like to sync the same workspace to a label but without deleting files that are not in the label. Like running the command p4 sync <workspace>/... @=label . 

I've tried many combinations of the populate command but all of them have run something like  p4 sync <arguments><workspace>/... @label 

Is there a way to run the p4sync command on jenkins so that it run a p4 sync ** @= command?*

Thanks!
