Triggers a deployment when Travis performs a build on specified branch and test suite.

travis-deploy.sh

#!/usr/bin/env bash

# What does this script do?
# This script will watch for a specific Travis $build_job on a specific
# $source_branch on the canonical GitHub repository and deploy build artifacts
# to $dest_branch on the git.remote specified in project.yml.

# How to use this script?
# This script should be executed in the `after_success` section of .travis.yml.
# It requires three arguments. Example call:
# `scripts/deploy/travis-deploy.sh build:validate:test master master-build`

build_job=$1      # The build job to to watch.
source_branch=$2  # The branch to watch.
dest_branch=$3    # The branch to which the build artifact should be committed and deployed.
DIR=$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )


# Note that the canonical repository is watched. Commits to forked repositories
# will not trigger deployment unless DEPLOY_PR is true.
