如何使用Go模块在特定分支上导入软件包

I'm reorganizing a repo from the following structure:

repo_root/
   |- foo/
       |- foo.go
   |- bar/
       |- bar.go
   |- go.mod

into the following:

repo_root/
   |- gosrc/
        |- foo/
             |- foo.go
        |- bar/
             |- bar.go
        |- go.mod

Now, inside foo.go of the original repo structure, I do something like below to import the package bar:

import "github.com/arb_name/repo_root/bar"

Now, with the new repo, I changed it to:

import "github.com/arb_name/repo_root/gosrc/bar"

Now, I run into the problem that go build of foo.go failed because

cannot find module providing package github.com/arb_name/repo_root/gosrc/bar

I certainly do not want to change the master branch of repo without first making sure that the restructure of repo works. I'm wondering if there is a way to solve my situation? I can work on my fork but ideally not directly making change to my fork's master.

Thanks!

Make sure that you updated your go.mod file to

module github.com/arb_name/repo_root/gosrc
