eclipse/scripts/setup_eclipse.sh

#!/bin/bash

# Quick script used to setup Eclipse for the ADT plugin build.
#
# usage:
#   setup_eclipse.sh [-p] <dest_dir>
#   -p: run Eclipse in the background and print its PID in dest_dir/eclipse.pid
#
# Workflow:
# - downloads & unpack Eclipse if necessary
# - *runs* it once


#-----------------
#
# Note: right now this is invoked by sdk/eclipse/doBuild.sh
# and it *MUST* be invoked with the following destination directory:
#
# $ setup_eclipse.sh /buildbot/eclipse-android/3.4.0/
#
#-----------------


set -e # abort this script early if any command fails
