Re: [cross-project-issues-dev] Simultaneous Release Overview

[David M Williams <david_williams@xxxxxxxxxx>]

This was a great overview. I did see one
inaccuracy about the aggregator including orbit bundles so I removed that
[1]. I also added some detail and links .. hopefully not so much as to
lose the 'overview' flavor. 

For future improvements .... 

The webtools project removing datatools
and using DTP due to cross-project communication is a poor example (just
historically inaccurate), but I couldn't think of a better one right now
so will improve that later. 

I also think it'd be nice to improve
the section on build technologies ... again, I can't do it real quick,
and others could probably do it better then I could, but I think the current
writeup is a little unclear, if not misleading. 

= = = = 
As for individual project builds, there are a few technologies
that are pretty well used. PDE Build is very common, but Hudson/Maven/Tycho
are gaining a lot of momentum. A common use case is to define a version-specific
build on Hudson. Hudson does the check out and invokes Maven on the project's
top-level pom.xml. Tycho can be configured to build an update site which
gets pushed out to our download server. 
= = = =

Perhaps others can clarify, but I think
PDE Build is used by all the other build technologies (Tycho/buckminster)
(that is, it is not "either/or"? But instead "Tycho/buckminster/maven"
all provide improved "dependency management" and ... ?  and
Hudson ... well, Hudson is an advanced cron job :)  to put it overly
simply, but could be said to " ... manage the build timing and additional
steps not related to the build per se, such as testing and style checking"?
Again, I suspect others can write better "overviews" of these
aspects of what is in use in Eclipse build infrastructure, I'm just saying
current paragraph could use improvement. Any volunteers? 

Thanks very much, 

[1] I still "owe" a writeup
on how projects should "include" orbit bundles in their features,
the brief reason being that products and patches are built on features.

Hey folks. I was asked recently to provide an overview
of how the
Simultaneous release is assembled. I couldn't find anything at the level
I needed on the wiki, so I cobbled something together. [1]

If you have a couple of cycles, please have a look to make sure that I
haven't misrepresented anything.

Thanks,

Wayne
