`go build -mod vendor` fails to make use of vendored packages

When deploying my Go services to Google AppEngine (standard), I receive an errors describing a module version not being found, while everything compiles fine.

The modules are on a private Github instance and checked out to vendor/.

A go build -mod vendor -o /dev/null ./... works in cloud-build-local, locally and in Google Cloud Build. A tag called 'v1.1.0' exists on github.com/company/gosystem:

gosystem$ git tag
v0.0.1
v0.0.2
v0.0.3
v1.0.0
v1.1.0

In the end I was able to make this work by forcing go to use vendor, by adding this to the go.mod:

replace github.com/company/gosystem => ./vendor/github.com/company/gosystem

Go uses https to fetch versions/dependencies. Even if you use vendor, Go will verify the version anyway. And since github.com/venclave/gosystem is a private repo, git can't get access to it.

There are few workarounds for this.

1 - Use ssh:

git config --global url.ssh://[email protected]/venclave.insteadOf https://github.com/venclave

2 - Use GitHub token:

Generate GITHUB_TOKEN here https://github.com/settings/tokens. 

export GITHUB_TOKEN=xxx
git config --global url."https://${GITHUB_TOKEN}:[email protected]/venclave".insteadOf "https://github.com/venclave"
