Automated merging of branches into master for travis-ci or any other ci

merge.sh

#!/bin/bash

git config --global user.email 'travis@travis-ci.org'
git config --global user.name 'Travis'
git remote set-branches --add origin master
git fetch
git reset --hard
git checkout master
git merge --ff-only "$TRAVIS_COMMIT"
git push git+ssh://git@github.com/${TRAVIS_REPO_SLUG}.git master

For automerge you need to use credentials to let travis access the repos, I used:

# must be already activated and synced in travis
cd git-repo/
travis sshkey --upload path/to/key

If you have no key, you can start like this:

travis sshkey --generate

If you just want to merge one branch into master use (you might want to fork my scripts):

language: python
cache: pip
sudo: required
script:
- echo "yes!"
branches:
  only:
  - next
