#
# This script mavenizes all dependencies from the Android SDK required to build Robolectric.
#
# Usage:
#   install-dependencies.rb
#
# Assumptions:
#  1. You've got one or more Android SDKs and Google APIs installed locally.
#  2. Your ANDROID_HOME environment variable points to the Android SDK install directory.
#  3. You have installed the Android Support Repository and Google Repository libraries from the SDK installer.
