Post-build arguments to batch script fails to convert build parameter - batch-file

Question

I'm using TFS 2013 and am building an Azure Cloud Service project that I want to package with Nuget so that I can publish to Octopus Deploy. I can't use octopack, because at the moment this is not supported. I'm trying to pass TFS parameters into a post-build batch script so that I can run nuget with -version parameters (which should change with each build).
The problem I'm having is that the batch script does not recognise the TFS build parameters. for example, in the script I want to pass an argument version $(TeamProject)-1.0.0$(Rev:.r), that would give the script the version to set in the package name.
The full nuget package call in the script is:
%nugetPath% push %packagePath%\Veedyo.%version%.nupkg
Passing this into the post-build script path works:
$/Application1/MAIN/Source/.NET/Application1.Package/package.cmd
This is because the source control path is translated into an actual path just after the build completes (and I can see the real path in the log).
However, the Post-build script arguments property in the build, doesn't convert this "$(TeamProject)"-1.0.0"$(Rev:.r)" to the desired value. this leads to an error executing the batch script:
Exception Message: TF270015: 'package.cmd' returned an unexpected exit code. Expected '0'; actual '1'. See the build logs for more details
So, does anyone have any idea how to convert add build parameter to the post-build script arguments property?

Answer 1

These macros are not available when you run the script. You can use one the the TF_BUILD environment variables listed here.
Probably, you are looking for TF_BUILD_BUILDNUMBER, or maybe you have to extract the data you are looking for; in this latter case Powershell can be simpler to use than cmd.exe interpreter.
