Well, no, probably not ... but, it will
take a lot of attention to get it done on time.
First greatest thanks to Kenn Hussey
for making (or fixing) an "early" contribution repository 
for EMF core (or, "base", I think they are now calling the platform-shared
This allows Eclipse 4.2 M2 and EMF M2
to both be installed from repository sites. (For full issues, and longer
term improvements, you can follow bug 356644).
Now the problem is that the new version
of EMF (and maybe Eclipse M2?), apparently, breaks numerous other
contributions, apparently due to increased minor version numbers (combined
with narrow ranges?).
To aggregate, at the moment, I would
have to disable about 20 of the b3aggrcon files in org.eclipse.juno.build.
I can (and may) do some disabling, ....
but, thought it would be a good time to review the process and timing of
making contributions to an aggregation build:
you do not have to wait until your +n
day to make a contribution. You can make a "warm-up" contribution
at any time ... especially if it is needed to allow the aggregation to
succeed. In other words, your +n day is the last possible day to make a
contribution ... not the first day you may make one.
Many of the current problems are "ripple
effects" from a few low level, commonly used bundles or features (in
modeling projects, it appears) so, maybe with only a few fixes we'll be
on the right path again, but, I ask that teams try to respond as quickly
as possible to fix any "aggregation errors" they get notified
about ... please do not think you can wait until your final contribution
next week ... and even if you have not been notified yet, if you use EMF,
please "peek ahead" with the M2 versions of Eclipse and EMF base
and prepare an early version, even if you re-contribute your final version
during the (final) window next week. After all, if we had to do a true
"iteration" waiting for each of 20 project to fix their builds
sequentially before the next one fixes theirs, then we will not finish
Thanks, for your attention, let us know
if questions or issues.
