Depot Path
The depot path is the full depot path of the project root folder. This is what will be checked out when a build occurs. Make sure to include the depot specific path and Perforce specific wildcard (...). Perforce labels are supported. However, you must uncheck "Let Hudson Manage Workspace View" and set the view up yourself. Additionally, when using a label, the recent changes history view in hudson will not show any history and you will not be able to tag (label) your builds.

Typical Example:
//depot/ProjectName/...
Using a label:
//depot/ProjectName/...@NightlyBuild

One Time Force Sync allows you to tell perforce to do a p4 sync -f //... which will make sure to pull down ALL files to the workspace, regardless if they have been sync'd before. Use this to get around a problem where the Perforce workspace became out of sync with what hudson actually has a copy of. For most users, you should never need to worry about this.

Note: this is reset after the next subsequent build.

First Changelist to Track allows you to specify the first changelist to start recording build history from. If you are adding an existing project, with lots of history, to Hudson, this will prevent out of memory errors and your first build from having thousands of change records.

Note: this is reset after the next subsequent build.
