Once you had update in TFS workspace for Jenkin TFS plugin, you might get error like bellow:

[workspace] $ "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\TF.exe" workspaces -format:brief -server:http://tfs.xxx.com:8080/tfs/Default ********
Collection: tfs.xxx.com\Default

The path D:\hudson\jobs\My build job\workspace is already mapped in workspace Hudson-My build job-MASTER;NAM\oldUser.
FATAL: Executable returned an unexpected result code [100]
ERROR: null

You should follow bellow steps to fix it:1. Remove the workspace: 

From VS:

1. Open Team Explorer
2. Click Source Control Explorer
3. In the nav bar of the tool window there is a drop down labeled "Workspaces".
4. Extend it and click on the "Workspaces..." option (yeah, a bit un-intuitive)
5. The "Manage Workspaces" window comes up. Click edit and you can add / remove / edit your workspace

From the command line

Call "tf workspace" from a developer command promt. It will bring up the "Manage Workspaces" directly!

2. Remove cache on this computer

By manually deleting all the files in the TFS cache, located here:

C:\Users\{UserName}\AppData\Local\Microsoft\Team Foundation\3.0\Cache

If there is a \4.0\Cache and \5.0\Cache existed, delete them all.
