Access parameter %build.counter% inside MSBuild project built by TeamCity

I have an MSBuild/C# project having a target trying to access `%build.counter% parameter supposed to be set by TeamCity.

<Target Name="TraceBuildParameters" BeforeTargets="BeforeBuild">
    <Message Text="Build.Counter=$(build_counter)" />
</Target>

I can access it in TeamCity project build settings but none of this work in the script:

build.counter // msbuild error
build_counter // null
system_build_counter // null
teamcity_system_build_counter // null
teamcity_build_counter // null

Is it possible to access this parameter at all, is it exposed?

Solution

  • TeamCity will send any system parameters to your MSBuild script (not configuration parameters). If you explicitly want the %build.counter% value, the easiest approach would be to set a system parameter as follows:

    system.BuildCounter = %build.counter%

    Then you should be able to reference it as $(BuildCounter).

    Alternatively, the build.number is already sent to MSBuild as $(build_number). Depending on whether or not you've customised the build number on the Configuration -> General Settings tab, this may save the need for the extra parameter.
