# $3 = the src zip (from out/host/eclipse/artifacts/RcpBuild-...)
# $4 = the destination directory (where the unpacked eclipse is created)
# $5 = the destination zip with the zipped eclipse ide.
# This rule is in used primarily to post process the .zip file that is
# generated by the Eclipse PDE build process. Ideally, we'd fix things in the PDE build
# itself, but since we don't know how we do this. These changes include:
# - Changing the product definition in eclipse.ini from org.eclipse.platform to ..adt.package.product
# - Setting eclipse.buildId in eclipse.ini
# - Setting eclipse.buildId in about.mappings
# - Changing the splash screen location from platform to adt.package in config.ini
# - Mac only: The PDE build produces eclipse.app and Eclipse.app folders. This is probably a bug
#   in the PDE build since the filesystems on Mac are case insensitive. In any case, eclipse.ini is
#   present only in eclipse.app, so we copy it over to Eclipse.app and remove the eclipse.app folder.
#   In addition, the root folder has a symlink to Eclipse.app/Contents/MacOS/eclipse. Since .zip files
#   don't support symlinks, this just gets copied over. We don't really need this file as users just
#   open the Eclipse.app application, so we just remove it. Lastly, the .icns file is manually copied
#   over and specified in eclipse.ini, only because including it directly in the product definition
#   causes the build on our servers to fail.
