How to use forked packages with dep golang?

Question

How can I use my own forked package easily using dep?

I would love to be able to use the upstream again when my changes are accepted.

Answer 1

While dep is no longer the prefered way of doing this, (go modules preferred as of go1.11)

With constraints this is easy, it will still be referenced everywhere in code and resolved via github.com/upstream/repo .

[[constraint]]
  name = "github.com/upstream/repo"
  branch = "forked-branch-name"
  source = "github.com/lexton/repo"
