What did you do?

In repository .git/config and $HOME/.gitconfig:

[url "ssh://git@PRIVATE_GITLAB/"]
    insteadOf = https://PRIVATE_GITLAB/
    insteadOf = http://PRIVATE_GITLAB/

I run go mod tidy -x -v inside repository nested module.

What did you see happen?

$ go mod tidy -x -v
go: finding module for package PRIVATE_GITLAB/PRIVATE_PROJECT/PRIVATE_REPOSITORY/pkg/utils
# get https://PRIVATE_GITLAB/?go-get=1
# get https://PRIVATE_GITLAB/PRIVATE_PROJECT/PRIVATE_REPOSITORY/pkg?go-get=1
# get https://PRIVATE_GITLAB/PRIVATE_PROJECT/PRIVATE_REPOSITORY/pkg/utils?go-get=1
# get https://PRIVATE_GITLAB/PRIVATE_PROJECT/PRIVATE_REPOSITORY?go-get=1
# get https://PRIVATE_GITLAB/PRIVATE_PROJECT?go-get=1

What did you expect to see?

I expect to see SSH protocol be used over HTTPS or HTTP but it still tries HTTPS after both gitconfig are configured

This is before git cloning. It needs to be able to determine the correct root of the repository. See GOAUTH or set netrc.

Unlike many projects, the Go project does not use GitHub Issues for general discussion or asking questions. GitHub Issues are used for tracking bugs and proposals only.

@seankhliao Can you elaborate ? I thought GOAUTH was not necessary since I am trying to use SSH protocol
