Is there a way to override a package?

Question

I have import statements in my code that look like this:

import "github.com/A/package"

It turns out that - temporarily - I need to use github.com/B/package.

Rather than modify the source, and re-modify it later, is there a way to specify an override?

What is "temporarily"? Why not just change the paths in `GOPATH` or `vendor/`? — JimB, Apr 10 '18 at 23:06
You could possibly move `github.com/A/package` and make a symlink to `github.com/B/package`. — Gavin, Apr 10 '18 at 23:52
@Gavin: symlinks are purposely not supported in GOPATH, you would need to rename the directories. — JimB, Apr 11 '18 at 01:26

Since Go1.11, modules allow the use of the replace directive in the go.mod file of the project. It allows to override an expressed dependency by another module.
