Guide to Maven 2.x auto completion using BASH

 First you must go to the following site to install the BASH programmable
 auto completion setup if your distro doesn't have it by default. I don't
 think many do so you'll need to go to the {{{http://www.caliban.org/bash/index.shtml#completion}Programmable Completion Website}}.

 Once you've setup your system for auto completion you need to take the
 following:

+----+

#!/bin/bash

_m2_make_goals()
{
  plugin=$1
  mojos=$2
  for mojo in $mojos
  do
    export goals="$goals $plugin:$mojo"
  done
}

_m2_complete()
{
  local cur goals

  COMPREPLY=()
  cur=${COMP_WORDS[COMP_CWORD]}
  goals='clean compile test install package deploy site'
  goals=$goals _m2_make_goals "eclipse" "eclipse"
  goals=$goals _m2_make_goals "idea" "idea"
  goals=$goals _m2_make_goals "assembly" "assembly"
  goals=$goals _m2_make_goals "plexus" "app bundle-application bundle-runtime descriptor runtime service"
  cur=`echo $cur | sed 's/\\\\//g'`
  COMPREPLY=($(compgen -W "${goals}" ${cur} | sed 's/\\\\//g') )
}

complete -F _m2_complete -o filenames mvn

+----+

 And place it in <<</etc/bash_completion.d/m2>>>. Once you've done that the
 next time you start up your BASH shell you will have m2 auto completion!
