# @brief Making eclipse packages
# @author Noriaki Ando <n-ando@aist.go.jp>
#
#------------------------------
#
# This script makes eclipse package for Linux, Windows and Mac OS X.
# It tries to download Eclipse SDK all in one package, and adds EMF,
# EMF Xcore, GEF, XSD and rtmtools, and makes them packaging again to
# be distributed.
#
# ** Environment variables
#
# The following vairables can/should be set to run this script.
#
# 1. Especially ECLIPSE_VERSION, DOWNLOAD_SITE, REPOSITORY, LANGPACK_URL
# have to be set appropriate value based on chosen eclipse version.
# Current default is eclipse 3.8.1
#
# 2. OPENRTP_SITE, WORK_DIR, PKG_DIR, OS and BIT can be set for your environment.
#
#
# - ECLIPSE_HOME: A directory path to an Eclipse SDK. Under this
#                 directory, .eclipseproduct, eclipse.ini, plugins and
#                 eclipse executable should exist. If this
#                 env.variable is not set, this script tries to search
#                 eclipse directory under some directories that is set
#                 in a env.variable ECLIPSE_DIRS written in the head
#                 of this script.
#
# - ECLIPSE_VERSION: Eclipse version string to be
#                 downloaded. Generally it would be R-x.y.z-<date>.
#
# - DOWNLOAD_SITE: Eclipse binary package download site URL. It should
#                 specify a directory contains eclipse binary.
#
# - REPOSITORY: Plugin repository URL of eclipse update site. This
#                 repository must contains eclipse official plugins
#                 such as EMF, GRF and XSD.
#
# - LANGPACK_URL: URL of language pack for Eclipse SDK package.
#
# - OPENRTP_SITE: OpenRTP tools update site for directory.
#
# - WORK_DIR: Working directory to download eclipse package, extract
#                 it and re-packaging it.
#
# - PKG_DIR: Created packages are stored this directory.
#
# - OS: Supported OS name of eclipse package.
#
# - BIT: Supported OS's platform
#

#------------------------------
# Global variables
#------------------------------
# These global variables are used in the script.
#
# ECLIPSE_DIRS: eclipse directory that is previously installed on the system.
#               This is only used for equinox to install plugins.
#
# ECLIPSE_<OS>_<BIT>: URL to Eclipse package for <OS> <BIT>bit
#               binary. <OS> and <BIT> should appear in OS and BIT global variable.
#
# PLUGINS: Plugins to be installed for OpenRTP tools.
#
# OPENRTP_PLUGINS: OpenRTP plugins without Japanese language pack
#
# OPENRTP_PLUGINS_NL: OpenRTP language pack.
#
# FILE_NAME: File name of downloaded eclipse package.
#
# URL: URL of downloaded eclipse packages.
#
# OPENRTP_JA_VER: OpenRTP (Japanese package) version string
#
# OPENRTP_EN_VER: OpenRTP version string
#
# EQUINOX_LAUNCHER: Equinox launcher jar file with path.
#
# NL_FILE_NAME: langpack file name.

# ** How to install plugins from command line

# org.eclipse.update.core.standaloneUpdate is obsolete. Now we should
# use org.eclipse.equinox.p2.director
#
# [OLD]
# java -jar <eclipse_dir>/plugins/org.eclipse.equinox.launcher_<ver>
#      -application  org.eclipse.update.core.standaloneUpdate
#      -command search -from <repository URL>
# Commands (install, uninstall, addSite, removeSite, search, enable, disable)
# See http://help.eclipse.org/indigo/index.jsp?
#     topic=/org.eclipse.platform.doc.isv/reference/misc/update_standalone.html
#
# [NEW]
# java -jar ~/eclipse-3.8/plugins/org.eclipse.equinox.launcher_<ver>.jar
#      -application org.eclipse.equinox.p2.director
#      -repository http://download.eclipse.org/releases/juno/
#      -installIU org.eclipse.emf.sdk.feature.group
