Build script

build.sh

#!/bin/bash
# run ./build.sh
# it will clone your existing repo and run the maven tests off this clone
# the branch tests are run from is the current branch at the time of cloning
#
# Note that you can work on the next bug while this is going on
#
# ./build.sh
# runs maven clean install
#
# ./build.sh test -pl module1,module2
# runs maven test -pl module1,module2
#
# For Mac OS users, if growlnotifier is present, a sticky notification will be sent upon build completion.
# 
# The environment variable BUILD_COMMAND should contain the command you want to invoke to run the build;
# I use this so I can forget how each process is built: I use scripts which jump to the right directory,
# set the right JVM and other necessary tools, including the value of this BUILD_COMMAND.
# In case of Maven projects a default is set; otherwise the value is mandatory.
#
# Many thanks to David Gageot (http://blog.javabien.net) for the inspiration and optimization of this script.
