[News.eclipse.technology.packaging] creating custom package locally with

[Mike Frysinger <vapier@xxxxxxxxxx>]

i'm trying to create a custom package that is basically the eclipse c/c++ package with a few additional plugins

while there are posts in this forum about doing this, it's been about the older hackfest method that people had to use with 3.4 and older.  i'm interested in the new p2 method.

there is this documentation:
http://wiki.eclipse.org/EPP/Galileo_Packages#Local_Package_Build

while that works fine to locally recreate one of the official epp packages, it isnt exactly bursting with details for creating your own derivative package.  so i thought i'd start off simple and try to recreate the official CDT package by using the local file:// method rather than the public URLs.

i started with the official RCP eclipse package.  then i imported the org.eclipse.epp.package.cpp and related .feature projects from cvs (using the URL in the aforementioned wiki page).  attempting to export these resulted in missing CDT errors, so i installed the CDT via the update manager.  now trying to use the "Eclipse Product export wizard" fails with this error:

Cannot complete the install because one or more required items could not be found.
Missing requirement: Eclipse IDE for C/C++ Developers 1.2.1.200909020128 (epp.package.cpp 1.2.1.200909020128) requires 'org.eclipse.platform.ide 0.0.0' but it could not be found
Software being installed: Eclipse IDE for C/C++ Developers 1.2.1.200909020130 (epp.package.cpp 1.2.1.200909020130)

googling for this error only results in hits about people unable to launch the initial eclipse.  no real hints as to where one can find this plugin.
