Run the command on a git clone (using current branch)

remote.sh

#!/bin/bash
# Clones your existing repo and run the subsequent command off this clone
# Tests are run on the the current branch at the time of cloning
#
# Note that you can work on the next bug while this is going on as
# tests are run off a cloned repo.
#
# $ remote.sh mvn clean install
# runs 'mvn clean install'
#
# A notification is sent upon build completion if your OS supports it:
# - on Mac OS, install Growl and grownnotifier
# - on Linux, install send-notify

For the record, I do the same thing with Jenkins. I have a whole bunch of jobs configured, but also one which build my current branch.
Two things are important there

• The right repo url. I use

   file:///<your-path-to-the-local-git-checkout>
  

• A way to switch the git clone to the right branch (the one which is active in your checkout). I do this via a Shell Command build step

  git checkout `(cd ~/work/hibernate/git/validator/; git symbolic-ref HEAD 2>/dev/null | cut -d"/" -f 3)`
  

With this setup I can also build my current branch on the press on the button while I still can continue working. On top of this I get a build history, logs, etc
