In v1, we do not exposed an option in the UI or otherwise to check whether the build machine is free or not. If the build machine is not free and you fire a build, you get an error back, which is fine. However, if you want to queue builds or pick one of the machines that is free, you need a way to check whether the build machine is free or not.
You can do this using the code below.
- Copy/paste the code below in a file called CheckBuildMachine.cs
- Compile the file using following command -
csc /r:%SystemDrive%\Windows\assembly\GAC_32\Microsoft.TeamFoundation.Build.Common\8.0.0.0__b03f5f7f11d50a3a\Microsoft.TeamFoundation.Build.Common.dll CheckBuildMachine.cs
- Run -
CheckBuildMachine <your team project> <your build machine>
to check whether the build machine is free or not.
The build machine is tied to one Team Foundation Server and can do one build per team project at a time. Multiple builds of different team project can be done simultaneously.
You can also use the zip file attached to download the complete solution and build it in VS.
Thanks,
Gautam
