Description:

Hi, I can't find a way to make my action run against the latest golang version available.

I want to run tests against stable golang releases but also verify that newer golang version do not provide harm to my codebase, for this reason I've setup my action to run on a version matrix and then have a "special job" that I want to run tests on the very latest golang release.

This is my setup:

      - name: Use golang ${{ matrix.go_version }}
        uses: actions/setup-go@v5
        with:
          check-latest: true

What I'd expect from this is that used golang version would be something > go1.22, instead I see golang 1.20 is being used.

Even adding cache: false makes my action run with golang 1.20

I understand this might not be a bug but just me not understanding the doc, but how am I supposed to reach my goal?

Action version:

actions/setup-go@v5

Platform:

• Ubuntu
• macOS
• Windows

Runner type:

• Hosted
• Self-hosted

Tools version:

Repro steps:

PR where I'm trying to fix the behavior:

Action result showing golang 1.20 is being used:

https://github.com/rond-authz/rond/actions/runs/7816281593/job/21321451154?pr=320#step:3:9

Expected behavior:

My test-latest job should run with the latest golang release avilable

Actual behavior:

not the latest is being used, regardless of the cache (apparently)
