utils/move_JDT_PDE_to_dropins.sh

#!/bin/bash -x

# JDT and PDE are built as update sites.
# The procedure of moving them to dropins is following:
#
# Copy Eclipse installation
# Install JDT or PDE into it
# Copy the difference into dropins
#
# This must go this way to initialize all the plugins.
#
# Arguments:
#  1: path to the location of the materialised IDE product
#  2: path to a repository that contains the plug-ins
#  3: the IDs of the plug-ins that should be moved to dropins
#
# Base Eclipse installation is required to not have plug-ins installed.
