What did you do?

Committed to my repository https://github.com/davidsbond/pkg, containing a cmd directory which has a main.go. I am using a tools.go file and vendoring to install the new binary like so:

tools.go:

//+build tools

package tools

import (
	_ "github.com/davidsbond/pkg/cmd/pkg-build"
)

The module I'm currently working with gets an error running go mod tidy when the module requires pkg.dsb.dev v0.0.0-20201009154706-060ec2f08e50 for package contents as well as the binary included in pkg/cmd/pkg-build.

When I remove the import line from the tools.go file, the modules download fine for that version. However, when I include the import in tools.go I get:

https://sum.golang.org/lookup/github.com/davidsbond/pkg@v0.0.0-20201009154706-060ec2f08e50

What did you expect to see?

The cmd/pkg-build folder to be downloaded and included in my vendor folder alongside the other packages in the module

What did you see instead?

I forgot I was using a vanity import. My bad.
