Check a file into TFS using Powershell - powershell

Question

As part of my continuous integration build I am creating an SQL script. This SQL script has to be checked back in to TFS after it is generated. I'm using the TFS Powertools in Powershell.
The code I used on my machine was:
Add-TfsPendingChange -Add -Item $filename | New-TfsChangeSet
This worked fine on my dev box because the folder I was in is mapped to a TFS workspace. When I move it to my build server it no longer works because TeamCity doens't map it's checkouts to a workspace it just pulls the files down.
How do I check files into a specific folder in TFS without being in a mapped workspace? Is that even possible?

Answer 1

I worked on something to do this for our continuous delivery project using GO. I got it working using a combination of PowerShell and the .NET assemblies provider with Team Explorer. I could not get it working purely in PowerShell (although there may be a way!)
The following script will check-in whatever is contained in the material path which is supplied as a parameter into the specified server path (also a parameter). You can also specify credentials to use and a url for the TFS server.
This code requires either Visual Studio or the TFS Team Explorer client to be installed. You need to provide the directory location of the assemblies to the script in the AssemblyPath parameter. If these assemblies are not found then the script will error and show which ones are missing.
NOTE: The code has not been checked for a while so there may be typos etc. If you have any problems let me know and I will try to help.
