Team Build Error: The Path ... is already mapped to workspace

Question

Use the command line utility TF - Team Foundation Version Control Tool (tf).

You can get a list of all workspaces by bringing up a Visual Studio Command Prompt then changing to your workspace folder and issuing the following commands:

C:\YourWorkspaceFolder>tf workspaces /owner:*

You should see your problem workspace in the list as well as it's owner.

You can delete the workspace with the following command:

C:\YourWorkspaceFolder>tf workspace /delete /server:BUILDSERVER WORKSPACENAME;OWNERNAME

Just delete the contents of the following folder(s):

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

Where UserName is actual or current user, and 3.0 is the version number.

I had a similar issue and to remove the workspace that was causing me a problem, I logged into another machine with TFS client installed and performed the following:

• On the File menu, point to Source Control, Advanced, and then click Workspaces....
• In the Manage Workspaces dialog box, tick the Show remote packages checkbox.
• Under the Name column, select the workspace that you want to remove, and then click Remove.
• In the Confirmation dialog box, click OK.

I received this error, which was caused by having two build definitions that pointed to the same source. The issue was that I used a static build directory in the Build Agent.

This forum post describes my issue and resolution exactly: http://social.msdn.microsoft.com/Forums/en-US/tfsbuild/thread/60a4138a-9b28-4c46-bdf4-f9775ce43c3e/

We had the same problem but deleting the workspace's from the TFS server did not work. (I should mention that I grabbed my colleagues VM that was already set up with his credentials.)

For me this worked: http://blogs.msdn.com/b/buckh/archive/2006/09/12/path-is-already-mapped-in-workspace.aspx

I just went into the : ...\Local Settings\Application Data\ made a search for VersionControl.config, opened up the folder that contained this file and deleted all of it's contents.

Previous to that I tried manually editing the file but it continued with the same error message.

I hope this helps.

For some reason I was having trouble deleting the workspace from the command-line utility. Luckily I found Team Foundation Sidekicks 2010 (from this post) which is free and provides a GUI for viewing and deleting TFS workspaces, and many more useful TFS features.
