TFS 2012构建PowerShell脚本中的更改集版本

Question

We have a TFS 2012 instance and a build agent w/ VS 2017. I am trying to modify a XAML build template to create a nuget package from a given project. I am required to put the changeset number in the description of the package but I am unable to get the correct value.

I have an InvokeProcess activity in the AgentScope of my template which runs a PowerShell script to pack the package. I have tried getting the TF_BUILD_* environment variables but none seem to be populated. I also tried BUILD_SOURCEVERSION with no luck. At the moment I am passing in the BuildDetail.SourceGetVersion value but that is returning the current changeset for the entire team project, not the specific project I am building.

What am I doing wrong? Are those variables only on the TFS server and not on the agent (build server)?

Answer 1

TFS 2012 build changeset version in PowerShell script

According to the article Build Script Hooks for TFS 2012 Builds :

When I created a script for a 2013 build to version the assemblies, I relied on the fact that the 2013 build sets some environment variables that you can use in your scripts.You can see I'm getting $env:TF_BUILD_BUILDNUMBER. Well, in the 2012 workflow, these variables aren't set, so you have to add an activity to do it .

That the reason why you tried getting the TF_BUILD_* environment variables but none seem to be populated.

So, to resolve this issue, you can just to follow the steps in Challenge 2 to set it.

Or, you can use TFS API to get the latest changeset number in your TFS version control:

Please see this thread for detailed information:

Programmatically retrieve the latest changeset number available in a workspace

Then you can write another small program to modify your description field in the .cs file be the changeset number you get in above.

Hope this helps.
