Dependencies file is not found. Supported file pattern: go.sum about setup-go

Hello @fmunteanu
Thank you for creating this issue. We will investigate it and get back to you as soon as we have some feedback.

I'm not sure what effect has disabling the cache related to build time, but when I do this, the warning is gone. From my understanding, starting with v4, caching is enabled by default. New step, with cache disabled:

      - name: Setup Go
        uses: actions/setup-go@v5
        with:
          cache: false
          go-version: 1.22.x

Workflow build step has no more warnings:

See #478.

Setting the step to (docs reference):

      - name: Setup Go
        uses: actions/setup-go@v5
        with:
          cache: true
          cache-dependency-path: |
            **/go.mod
            **/go.sum

Produces another warning, see Post Setup Go step in workflow:

This also happens in https://github.com/petermattis/goid because that library has no dependencies, and Go doesn't create a go.sum file unless there are at least some dependencies.

It would be good to avoid the warning in such cases.

Hi @fmunteanu, The below workflow file have resolved the warning message issue. By adding steps to create the mod cache directory and cache the modules, we ensured that the cache folder path exists before it's accessed by the cache action. This eliminates the warning about the cache folder path not existing on the disk.
Going forward, this setup should provide a smoother run for your Go workflows. If you encounter any more issues or have other questions, don't hesitate to ask.

Hello @fmunteanu
Just a gentle reminder!
