Specifies the contents of the script. The maximum supported inline script length is 500 characters. Use a script from a file if you want to use a longer script.

failOnStandardError - Fail on Standard Error
boolean. Default value: true.

If the value of this boolean is true, the task fails if any errors are written to the error pipeline or if any data is written to the Standard Error stream. Otherwise, the task relies on the exit code to determine failure.

Task control options

All tasks have control options in addition to their task inputs. For more information, see Control options and common task properties.

Output variables

None.

Remarks

PowerShell@1 runs only on Windows agents. To run PowerShell on other agent types, use PowerShell@2.

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.

Set a variable so it can be read by subsequent scripts and tasks

Passing pipeline secrets in script, but secret is not masked in pipeline logs

Be aware that PowerShell cuts off error messages, so if you use pipeline secrets in a script, the secrets could be trimmed and exposed. For example, in the inline script below:

./script.ps1 --arg1 value1 --arg2 <some_secret_which_will_be_masked_here>

There could be an exception like: At <path_to_temp_script_file>:4 char:3:

+   ./script.ps1 --arg1 value1 --arg2 <unmasked_part_of_original_secret> ...
+   ~~~~~~~~~~
    + <Additional exception details>

To avoid this issue, you can handle these exceptions on a script level, or avoid cases when pipeline secrets could appear in source code lines within error messages.
