No bash in PATH on self-hosted Windows runner

[Alexolut]

When I initially tried to use conan-io/setup-conan@v1 I stuck with an error:

Error: bash: command not found

Turned out that my self-hosted Windows runner doesn't have bash visible to run command. I google a bit for such error and found that it can be resolved by adding bash from Git installation, so I added additional step in my workflow file before setup-conan action:

- name: Add Git Bash to PATH
  run: |
    echo "C:/Program Files/Git/bin" | Out-File -Append -FilePath $env:GITHUB_PATH -Encoding utf8

It works, but probably there's more elegant way and can be somehow addressed internally by conan-io/setup-conan.
What do you think?

@Alexolut Hello, could you please share your GHA file used and the link to your build error?

Running bash on Windows builds is something natively supported by GHA: https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-syntax#defaultsrunshell

Are you running a custom build, like on your local machine as a slave node?

Hi, @uilianries. I'm not able to share file or link to error since it located on private org repo. We use custom Windows machine as a runner, i.e. runs-on: our-custom-runner. For some reason there's no bash visible by default. Maybe we can consider updating our build image to make bash visible.

But as I mentioned earlier adding a path to git/bin folder into PATH variable solves the issue. We also able to run shell: pwsh commands.

Regarding the initial issue I found several similar cases, e.g.:

• Windows fails: bash: command not found subosito/flutter-action#302
• Issue on windows - Error: bash: command not found subosito/flutter-action#174
• windows-arm-latest-large: bash: command not found actions/runner-images#11635
