Specify the name of the Perforce workspace to be used as the Jenkins build workspace. If the workspace does not yet exist, the configuration will be saved in Jenkins; the workspace is created only when it is to be used. If the workspace exists and you are connected to a Perforce server the auto-text fill should list suitable workspaces; updates are only applied when the workspace is used.
Workspace names can use variable substitution using the specified ${VARIABLE} variables.
Variables can be taken from the Jenkins Environment or Parameterized builds
