Hi @hasheddan,
Wonder if you know anything about this. Prior to this PR, we have a "Cache Go Dependencies" step, which uses .work/pkg as its target path to be cached. And it gives the following warning:

If I interpret this correctly, it complains because at the end of the job run, the target path (to be cached) .work/pkg does not exist. I gave a try to make build.all locally, and this was indeed the case, that directory does not get populated.

Do you know how does the .work/pkg directory gets populated?

@ulucinar it looks like this PR drops the Go dependency caching -- are you saying you get the path miss when it is not dropped?

Yes, correct. That caching was never working because the action cannot find the module cache under .work/pkg. So I just removed that target with this PR. However, we are also building a Go executable (uptest) in this repo and I wonder why the mod cache does not get populated with our common build targets. Do you have any insights? I searched for references of GOPATH in the common build module and cross-checked the official provider repos to see whether we explicitly set GOPATH in our makefiles.
