The PowerShell build runner is specifically designed to run PowerShell scripts.
List of PowerShell versions supported by TeamCity. It is passed to
PowerShell run mode
Select the desired execution mode on a x64 machine.
Specify how the error output is handled by the runner:
Specify the path to the build working directory.
Select whether you want to enter the script right in TeamCity, or specify a path to the script:
Script execution mode
Specify the PowerShell script execution mode. By default, PowerShell may not allow execution of arbitrary
Available if "Script execution mode" option is set to "Execute .ps1 script from external file". Specify here arguments to be passed into PowerShell script.
Additional command line parameters
Specify parameters to be passed to
Interaction with TeamCity
Attention must be paid, when using PowerShell to interact with TeamCity through service messages.
PowerShell tends to wrap strings written to the console with commands like
Write-Error and similar (see TW-15080). To avoid this behavior, either use the
Write-Host command, or adjust the buffer length manually:
Due to this issue in PowerShell itself which causes zero exit code to be always returned to a caller, TeamCity cannot always detect whether the script has executed correctly or not. We recommend several approaches that can help in detecting script execution failures:
Manually catching exceptions and explicitly returning exit code
Since TeamCity 9.0 the PowerShell plugin does not use the cmd wrapper around
powershell.exe. It makes returning the explicit exit code possible.
- Setting Error Output to
Errorand adding build failure condition
In case syntax errors and exceptions are present, PowerShell writes them to
stderr. To make TeamCity fail the build, set Error Output option to
Errorand add a build failure condition that will fail the build on any error output.
Failing build on certain message in build log Add a build failure condition that will fail the build on a certain message (say "POWERSHELL ERROR") in the build log.
The PowerShell support is implemented as an open-source plugin. For development links refer to the plugin's page.
