Properties

powershell string. Required as first property.
Inline PowerShell script.

errorActionPreference string.
Unless otherwise specified, the error action preference defaults to the value stop. See the following section for more information.

failOnStderr string.
Fail the task if output is sent to Stderr?

ignoreLASTEXITCODE string.
Check the final exit code of the script to determine whether the step succeeded?

workingDirectory string.
Start the script with this working directory.

condition string.
Evaluate this condition expression to determine whether to run this task.

continueOnError boolean.
Continue running even on failure?

displayName string.
Human-readable name for the task.

target target.
Environment in which to run this task.

enabled boolean.
Run this task when the job runs?

env string dictionary.
Variables to map into the process's environment.

name string.
ID of the step. Acceptable values: [-_A-Za-z0-9]*.

timeoutInMinutes string.
Time to wait for this task to complete before the server kills it.

Note

Pipelines may be configured with a job level timeout. If the job level timeout interval elapses before your step completes, the running job (including your step) is terminated, even if the step is configured with a longer timeoutInMinutes interval. For more information, see Timeouts.

retryCountOnTaskFailure string.
Number of retries if the task fails.

Remarks

The powershell keyword is a shortcut for the PowerShell task. The task runs a script using either Windows PowerShell (on Windows) or pwsh (Linux and macOS).

Each PowerShell session lasts only for the duration of the job in which it runs. Tasks that depend on what has been bootstrapped must be in the same job as the bootstrap.

Error action preference

Unless otherwise specified, the error action preference defaults to the value stop, and the line $ErrorActionPreference = 'stop' is prepended to the top of your script.

When the error action preference is set to stop, errors cause PowerShell to terminate the task and return a nonzero exit code. The task is also marked as Failed.

errorActionPreference: stop | continue | silentlyContinue

steps:
- powershell: |
    Write-Error 'Uh oh, an error occurred'
    Write-Host 'Trying again...'
  displayName: Error action preference
  errorActionPreference: continue

Ignore last exit code

The last exit code returned from your script is checked by default. A nonzero code indicates a step failure, in which case the system appends your script with:

if ((Test-Path -LiteralPath variable:\LASTEXITCODE)) { exit $LASTEXITCODE }

If you don't want this behavior, specify ignoreLASTEXITCODE: true.

ignoreLASTEXITCODE: boolean

steps:
- powershell: git nosuchcommand
  displayName: Ignore last exit code
  ignoreLASTEXITCODE: true

Examples

steps:
- powershell: Write-Host Hello $(name)
  displayName: Say hello
  name: firstStep
  workingDirectory: $(build.sourcesDirectory)
  failOnStderr: true
  env:
    name: Microsoft
