How to call PowerShell script with GitHub Actions workflow?

Question

I'm calling .\build.ps1 and it seems to hang:

Do I need something special? In AzureDevOps this was working out of the box.

Not sure if you have to specify shell to be run but I'm currently experiencing similar issue with my action (bash script). Already opened a ticket, but it's yet to be processed. — Robert Dyjas

As agreed in the comments, the solution for this issue was to specify the shell to be run in your Action file. In your case you had to change from:

    - name: Build
      run: |
        .\build.ps1

to:

    - name: Build
      shell: pwsh
      run: |
        .\build.ps1

For more details about available values for shell param, refer to documentation.

The example with shell: pwsh is equivalent. The default shell for windows is pwsh, thus it is not necessary to specify it.

@MircoT and it's still required to be specified for non-Windows

Yes, but the workflow mentioned in the question was already windows-latest. This is why I don't understand the suggestion...

I think what happens is that when @Robert answered this question in 2019, pwsh was not the default back then

I tried with a self runner windows 2019 and got error as pwsh: command not found
