Does anyone have a git commit hook I can use that will ensure a JIRA issue number appears in the checkin message? I've got no experience driving JIRA from a git commit hook so any help would be appreciated -- working source even more so!
Open a Jira issue then go to the Git Commits tab. In this tab, you will see commits, files changed, links to external repository, commit author and more. git commit message to link the commit to this issue. The git commit will get associated with the Jira issue if the commit message includes the exact issue ID.
The commit-msg hook takes one parameter, which again is the path to a temporary file that contains the commit message written by the developer. If this script exits non-zero, Git aborts the commit process, so you can use it to validate your project state or commit message before allowing a commit to go through.
The commit-msg hook is much like the prepare-commit-msg hook, but it's called after the user enters a commit message. This is an appropriate place to warn developers that their message doesn't adhere to your team's standards. The only argument passed to this hook is the name of the file that contains the message.
First, make the hook executable:
chmod a+x .git/hooks/commit-msg
Append the following lines, substituting PROJECT with your project's code.
test "" != "$(grep 'PROJECT-' "$1")" || {
echo >&2 "ERROR: Commit message is missing Jira issue number."
exit 1

#
# Update JIRA with git commit messages
#
# == Usage ==
#
# To update a JIRA issue, prepend the first line of your git commit
# message with the issue key and a colon:
#
# $ git commit -m "GIT-1: Updates something"
#
# A comment will be added to the GIT-1 issue that looks something
# like:
#
# Commit: <Hash>
# Author: Bob Example <[email protected]>
# Date: Mon Jul 14 14:00:00 -0400 2008
#
# GIT-1: Updates something
#
# To change an issue's status, append an action string:
#
# GIT-1 resolved: Updates something
# GIT-1 closed: Finishes this
# GIT-1 reopen: Starting work on this
#
# To update multiple issues, separate them with a comma:
#
# GIT-1, GIT-2: Adds comments to GIT-1 and GIT-2
# GIT-1, GIT-2 resolved: Updates GIT-1 and resolves GIT-2
#
# == Installation ==
#
# To get this working, first install a few gems:
#
# $ gem install soap4r
#
# Now, jira4r, which has to be pulled down from subversion:
#
# $ svn co http://svn.rubyhaus.org/jira4r/trunk jira4r
# $ cd jira4r
# $ gem build jira4r.gemspec
# $ gem install jira4r-*.gem
#
# And finally, grit, a Ruby git library. As of today (July 14, 2008),
# the most updated fork is being maintained by Scott Chacon on github.
# For whatever reason, my attempt to install the gem directly wasn't
# working (doesn't appear to be exposed?), so I cloned and installed
# directly:
#
# $ git clone git://github.com/schacon/grit.git
# $ cd grit
# $ gem build grit.gemspec
# $ gem install grit-*.gem
#
# When the gem gets fixed, it should be a simple:
#
# $ gem sources --add http://gems.github.com
# $ gem install schacon-grit
#
# Now just copy/symlink/move an executable copy of this file into your
# .git/hooks directory (be sure not to overwrite an existing hook):
#
# $ cp jira-post-receive /path/to/repo/.git/hooks/post-receive
#
# And don't forget to update some globals below. Voila. You should
# be in business.
#
# == TODO ==
#
# * Get status changes with comments working.
#
require "rubygems"
require "jira4r/jira_tool"
require "grit"
# Don't forget to set these.
#
# I'd recommend creating a dedicated user in JIRA to execute these
# updates. That user will need permissions to:
#
# * Browse Projects
# * Resolve Issues
# * Close Issues
# * Add Comments
#
# (I think that's comprehensive.)
