Hi Nick,
Thank you for the reply. I'm finally getting back to this problem after
getting sidetracked yet again. I'm not really getting anywhere, unfortunately.
I'm by no means a build expert/release engineer of any sort, so please bear
with me.
We don't use CVS at all, so for me, the gef example fails saying "[build]
[eclipse.fetch] Could not retrieve feature.xml and/or build.properties:
java.io.IOException: Cannot run program "cvs" (in directory
"C:\tmp\build\N200910221443\eclipse\tempFeature"): CreateProcess error=2, The
system cannot find the file specified.". I'm not sure installing and
configuring CVS is a good use of my time, just to make an example work. So, for
simplicity's sake, I figured I'd try again to get it working manually within
the PDE UI before I tried making sense of the scripts and ant tasks. If I
can't get it working manually, I can't see how I have any hope of automating
it. So, this is what I did:
1. Created a feature that contains all of my plugins (3) and fragments (2), and
includes my feature (which in turn also includes the 3 plugins).
2. Created an update site
2a. Added my master feature
2b. Built the site. It generated jars for the master feature, my
feature, and for each of my 5 plugins/fragments, as well as the artifacts.jar
and contents.jar.
3. Start a clean debug instance of eclipse with none of my workspace plugins
enabled.
3a. Add the local update site
3b. Install the "all in one" feature
3c. Let Eclipse it restart itself.
My feature is listed as installed software (under Help -> About -> Installation
Details), but none of my plugins are listed in the plugin registry, nor are the
GUI elements being loaded. It's also not showing up under "Features" in the
Installation Details box. I'm obviously missing something fundamental. If in
step 2a, I also add my other (non-master) feature to the update site, then in
step 3b try to install that one instead, I get the same result. What I find
rather odd is that in the list of installed software, the ID is
feature.a.feature.group. Where's this "feature.group" thing coming from? I
don't get the error I was having previously any more (I think there may have
been a spurious dependency on one of my plugins in my feature), but I'm not
exactly getting any further, either.
Thanks for your help,
Kristina

Assuming you need to build, and *rebuild* this once in a while, and have little
overhead involved in doing so, have you considered doing a headless (not with
Eclipse PDE/UI) build, and generating an update site zip?
Easiest way to do that, IMHO, is to use Athena. It will also run your JUnit
Plugin Tests, if you have any, as part of the build. If you're on Linux. (On
Mac/Win, YMMV.)
Getting started w/ an Athena-style build (which is really Eclipse PDE/Build
wrapped with some goodies to make it easier):
http://wiki.eclipse.org/Common_Build_Infrastructure/Getting_Started/Build_In_Eclipse
The sample project outlined there is for the GEF project; once you get it
working, you can use the same concept to do a build for your own
plugins/features, and by default you'll end up with an update site zip
(complete with p2 metadata). Unpack that zip onto some server, and voom
- update site!
Only requirement is that you create a feature which contains everything you
want on the site, often called the "all-in-one" or "master" feature.
It can contain both features & plugins (feature.*, plugin.*, fragments).
Once you have it working in Eclipse, you can then wrap it with some CI engine
(like Hudson, Cruise Control, etc.) and have it run automatically on a schedule
or when your sources change.
If you have any problems, don't hesitate to ask here or in dash-...@eclipse.org.
