Maven is a build system used by many Java-based projects. Some folks
have added Git support, allowing the inclusion of build identifiers
(like branches and commit hashes) in products of Maven builds. But
they need help to complete it. Is anyone interested in helping?

This is something we (Mifos) need, so if you do help, know that
you'll be helping to end world poverty.

FYI, I gave up trying to fix the integration tests, or to modify the
plugin to suit my needs. I instead used groovy script right in my
POM, and set project properties that are filtered into a file
included in our war.

Here's the Groovy snippet I used, modified to have shorter names to
prevent wrapping:

  def env = System.getenv()
  def gitcmd = "git"
  if (env['OS'] =~ /^Windows/)
      gitcmd = "cmd /c ${gitcmd}"
  def gcmd = """${gitcmd} log --pretty=format:%H -n1""".execute()
  project.properties['mifos_commit'] = gcmd.in.text
  project.properties['mifos_build'] = env['BUILD_TAG'] ?: 'DEV'
  project.properties['mifos_date'] = "" + new Date()

"BUILD_TAG" is something set by the Hudson continuous integration
server (that's what we use).

Here's the script, in vivo (commit 5dfe4d1abda09713b296ea2524):

I figured trading lots of lines of Java, XML, etc. for 8 lines of
maintainable/portable Groovy was a good move.

Hope this helps someone else using Maven and git who needs build
identifiers available as properties,
