Team Foundation Server 2012 Build Global List Problems


My experience with the upgrade and use of TFS 2012 has been very positive. I did come across a couple of issues recently that tripped things up for a while.

ISSUE 1

The first issue is that 2012 prior to Update 1 published an invalid build list item value to the collection global list. In 2010, the build global list, list item value syntax is an underscore between the build definition and the build number. In the 2012 RTM this underscore was replaced with a backslash, which is invalid.  Specifically, an upload of the global list fails when the backslash is followed at some point by a period. The error when using the API is:

<detail ExceptionMessage="TF26204: The account you entered is not recognized. Contact your Team Foundation Server administrator to add your account." BaseExceptionName="Microsoft.TeamFoundation.WorkItemTracking.Server.ValidationException"><details id="600019" xmlns="http://schemas.microsoft.com/TeamFoundation/2005/06/WorkItemTracking/faultdetail/03" /></detail>

when uploading the global list via the process editor the error is:

This issue is corrected in Update1 as the backslash is changed to a forward slash.

ISSUE 2

The second issue is that when upgrading from 2010 to 2012, the builds in 2010 are not published to the 2012 global list.  After the upgrade the 2012 global lists doesn’t have any builds and only builds run in 2012 are published to the global list.

This was reported to the MSDN forums and Connect.

To correct this I wrote a utility to pull all the builds and recreate the builds global list for each project in each collection.  This is a console application with a program.cs, a globallists.cs and a app.config (not published here).

The utility connects to TFS 2012, loops through the collections or a target collection as specified in the app.config. Then loops through the projects, the build definitions, and builds.  It creates a global list for each project if that project has at least one build. Then it imports the new list to TFS.  Here’s the code for program and globalists classes.
