Our aggressive plan (in attached note) is working out pretty well. Thanks
to Pascal making p2 (and other) changes, and thanks to Tycho Team for
making required changes and fixes to 0.23.0-SNAPSHOT. Our Platform
I-builds (downloads and repositories) from this week all have the new "Mac
App" layout.
And, I have just "published" a warm-up I-Build to the staging repo that
will have the new "Mac App" metadata (for the "Mac Platform/SDK
products").
And, that's the reason for "Caution:". We have known all along that you
(nor users) will be able to "update" from old layout, to new layout -- you
have to "start fresh" with Mars (which, IMHO, is always a good idea) BUT
... as things are right now, p2 will TRY to update, and leave your
installation in a broken state. So, don't do that. We still hope to fix
this for M6 but as of this minute, we do not know how to. You might want
to follow bug Bug 462282 for that issue.
In the meantime, don't "update" Mac "product" installations from staging
(nor, our ../eclipse/updates/4.5-I-builds) repository. "Start fresh"
instead ... and then future updates will work fine.
Oh, and at the moment, we may not be able to actually "sign" the
executable apps for M6 ... the main reason for going through this grief!
... still watching
infrastructure bugs (Bug 462373 and Bug 445050).
And, I will end with one "tip". While there is hope getting the new layout
may eventually be "completely transparent" (Bug 461606), for M6, using
Tycho 0.23.0-SNAPSHOT, if you have a "product" section in your pom, it
might look something like this:
<goals>
<goal>materialize-products</goal>
</goals>
<configuration>
<profile>SDKProfile</profile>
<products>
<product>
<id>org.eclipse.platform.ide</id>
<rootFolder>eclipse</rootFolder>
</product>
</products>
</configuration>
But will have to be changed to add a <rootFolders> element similar to
this:
<goals>
<goal>materialize-products</goal>
</goals>
<configuration>
<profile>SDKProfile</profile>
<products>
<product>
<id>org.eclipse.platform.ide</id>
<rootFolder>eclipse</rootFolder>
<rootFolders>
<macosx>Eclipse.app</macosx>
</rootFolders>
</product>
</products>
</configuration>
Good luck!

Subject: [cross-project-issues-dev] Heads up: Platform will be
"coming in hot" with M6 changes for "Mac App" layout
Sent by: [email protected]
Extended team,
I wanted to make everyone aware of our latest Platform plans for M6 ...
especially since it has the potential to effect "downstream" consumers and
contributions to Mars Sim. Release. If anyone sees any "blocking" aspects
to this plan, let us know.
In short, we will aggressively be trying to get changes needed to build
our "Mac Product" in a relatively standard "Mac App layout". See
Bug 431116 - Releases for Mac OS X should be bundled as a proper "Mac App"
and/or "Library"
We felt it important to make the move by M6, to be sure problems/issues
can be found, and fixed, by M7 ... otherwise, we face a greater risk
making changes during RCs, or, worse, not having it well tested by anyone
or no time to make important fixes.
Some issues are listed below ... may be others?
- To do this, we will soon have to move to Tycho 0.23.0-SNAPSHOT.
-- always risky to do a milestone with a "SNAPSHOT", but ... we think
worth it in this case. (And we'll ask Tycho team to be "extra careful" :)
-- so far, we can not quite get our "production build" to work with it ...
but, suspect we can soon.
-- For an "experimental build", see
http://download.eclipse.org/eclipse/downloads/drops4/X20150309-0218/
--- (This was produced with a locally built "patched" Tycho, and so far
haven't quite got the "official" SNAPSHOT to work consistently ... but
works sometimes, and issues appear unrelated to the "Mac layout")
- The change is "all or nothing" ... once we (and Tycho) move to this new
layout, the old layout will no longer be possible.
* This should only effect consumers who create their own "products" ...
should not effect "features" or "plugins" in any way.
* Should not effect Linux or Windows "products" in any way.
* But, anyone who does produce "products", for the Mac, will also have to
use Tycho 0.23.0-SNAPSHOT for "Sim. Release".
* Effect on "PDE Builds" and "Buckminster builds" is sort of unknown (by
us) ... ?
We have set our own deadline of Sunday March 15 to "have everything
working" ... and, if not by then ... *might* have to back peddle, or come
up with some other plan.
Just wanted to give a little early warning of this change coming. I think
for the most part, everyone will welcome the change, but may be some rough
spots ahead.
Please comment in Bug 431116 if you see issues, or open new bugs, having
them 'block' that bug.
Thanks,
