(I sent this one previously to help-guix two days ago, and again one day
ago, but it seems that it did not end up in
<https://lists.gnu.org/archive/html/help-guix/2022-03/threads.html>
so I'm resending to guix-devel this time)

Hi,

I'm trying to package go-github-com-hashicorp-vault-sdk.
I ran "guix import go github.com/hashicorp/vault/sdk", corrected
the commit and (for now) remove the inputs (many aren't packaged yet).

When I now try to build it, I end up with the following error
message (from "guix build"):

  phase `patch-source-shebangs' succeeded after 0.6 seconds
  starting phase `build'
  package github.com/hashicorp/vault/sdk: no Go files in /tmp/guix-build-go-github-com-hashicorp-vault-sdk-0.4.1.drv-0/src/github.com/hashicorp/vault/sdk
  Building 'github.com/hashicorp/vault/sdk' failed.

However, there is go stuff there!

$ ls /tmp/guix-build-go-github-com-hashicorp-vault-sdk-0.4.1.drv-4/src/github.com/hashicorp/vault/sdk
> database  framework  go.mod  go.sum  helper  logical  physical  plugin  queue  README.md  version

There's a go.mod, go.sum and the subdirectories have .go files!

Does anyone know how to resolve this kind of problem?

Greetings,
Maxime.
