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

When creating a new build in Team Foundation Server, I get the following error when attempting to run the new build:

The path C:\Build\ProductReleases\FullBuildv5.4.2x\Sources is already mapped to workspace BuildServer_23.

I am unable to see a workspace by that name in the workspaces dialog.

Solution 1:

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

Solution 2:

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.

Solution 3:

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.

Solution 4:

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.
