Wondering if "$?" could be used...
http://tldp.org/LDP/abs/html/exit-status.html

ERRORLEVEL=$? ?

That's the idea.
I think I found something easier with Bash pipe management. Have to try ${PIPESTATUS[0]} and set -o pipefail

mvn  $@ | blabla
errorlevel = ${PIPESTATUS[0]}

or

set -o pipefail
mvn  $@ | blabla
errorlevel = $?

Who, this code froze my system...

set -o pipefail

mvncolor()
{
  mvn $@ | blabla
  exit_status=$?

  blabla

  exit $exit_status
}

alias mvn="mvncolor"

mvn clean install # Freeze!

myecho()
{
  [ -x /usr/bin/notify-send ] && notify-send $*
  echo $*

works on ubuntu 12.10

Just need to add a trap for term/exit (to reset formatting) and it should be ok. I'll try to do that tomorrow if I find some time.
