go get:由-mod = vendor禁用

I'm using Go modules, and I use vendoring mode, as it speed up 2x my CI.

I do:

go mod vendor
go build -mod=vendor ...

and I can build my app without any issue.

But when I want to use go get, for instance to install golint:

go get -u golang.org/x/lint/golint

It will download all my project dependencies again, not just golint.

If I try:

go get -mod=vendor -u golang.org/x/lint/golint

I get:

go get: disabled by -mod=vendor

Lint will be used in my dev docker image, but not in the prod one, so I don't want to add it to go.mod

What can I do about it ?
