[cbi-dev] Granularity of current Tycho build of eclipse sdk

[David M Williams <david_williams@xxxxxxxxxx>]

If I may ask another, probably "dumb
question", What was the point, exactly, of "building everything
at once"? I know there was an initial effort to build equinox, and
then the platform, and then jdt and pde and at the time that failed because
the "repositories were not correct" for that approach. I'm wondering
if thing have improved enough (in Tycho or understanding) that the Tycho
builds could be more "feature driven" now? 

I'm not sure about "platform and
equinox" that might be hopelessly intertwined due to intertwined history,
but seems to me the Platform-plus-equinox, JDT, and PDE, should be easily
separable? 

I'm fairly sure they would be for PDE
and the only reason no effort was made in the past was so that everything
could be included in one big zip to "ship over" from IBM machines,
to eclipse.org machines for signing, and then shipped aback, and packaging
and tests continue from there. 

I am asking to try and catch up my education.
Is Tycho "repo driven"? Or can it be made to be "feature
driven"? I think the answer will give me (us all) a good idea of what
kind of simplifications could be made in the future, since, I believe,
part of the goal of this transition is to end up with simpler, easier to
understand builds. 

Thanks for any pointers,
