I might pick up this PR and finish it. This is causing disruptions for my company.

This PR appears to break two tests, I will attempt to remedy this.

Ah yes, my git configuration wasn't setup to convert line endings back to UNIX-style. I'll fix it some time today if I get some time.

I've pushed a version with only the changes to the TypeScript source files here: https://github.com/AceCoderLaura/checkout/tree/finishing-628-no-compile I will have to ask you to build the project yourself because I've run out of time to fix the line endings issue. Hope this helps!

I got some more time to work on this today and successfully transpiled the change to index.js without any disruptions to the line endings.

Hitting the same issue. Will this ever be merged?

[AceCoderLaura]

We're still using this fork but it's getting stale and it now has conflicts with the main branch. I haven't tried the latest version, does anyone know if this is still an issue in the main branch? If it is, I'll make some time to update the forked version.

I ran into this issue recently. For me, a file in a submodule got modified by a previous run and then was present in the next run, causing issues.

It would be nice if this got merged so I can have reliable CI without adding hacks.

This was my workaround by the way:

      - uses: actions/checkout@v3
        with:
          submodules: true
      - name: Submodule cleanup fix  # Bodge for https://github.com/actions/checkout/issues/358
        run: |
          git submodule foreach --recursive git clean -ffdx
          git submodule foreach --recursive git reset --hard
