Environment Variables

Global environment variables to be passed down to all hooks and builds.

This is useful for GO111MODULE, for example. You can have your .goreleaser.yaml file like the following:

# .goreleaser.yml
env:
  - GO111MODULE=on
before:
  hooks:
    - go mod download
builds:
- binary: program

This way, both go mod download and the underlying go build will have GO111MODULE set to on.
