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

Question

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.

Answer 1

Use the command line utility tf.

You can get a list of all workspaces by bringing up a Visual Studio Command Prompt and using the following command:

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

Answer 2

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.
