I just notice that the "Example Plug-ins"
(org.eclipse.sdk.examples-3.6.zip) available from

http://download.eclipse.org/eclipse/downloads/drops/R-3.6-20 1006080911/index.php

have their features within jars. Is this an extended functionality of
Eclipse features?

Now, adding these examples to the Eclipse 3.6 distribution I notice that
the SWT examples cannot be read and I get an error report
within the Error View:

Unable to find feature.xml in directory: C:\Program
Files\Eclipse_3.6.x\features\org.eclipse.sdk.examples_3.3.0. v20100527-817fFcfFEdcVbpRlgyBRcVX.jar

Does that mean that the above assumed new feature is buggy or is it so,
that the Example Plug-ins package has been incorrectly build?

To get the examples running, I tried to unpacked both jars (as if the
jars were zip files) into directories of the same name (modulo
extension) but this time I get another error:

Any ideas?

Did you install them, or have eclipse install them? or did you copy
them into eclipse? I believe they're in their p2 format (runnable
features are always directories, in a p2 repo they are jars). Maybe the
code that installs them hasn't twigged to the fact they're p2 repos.

If you have the examples.zip, can you use Help>Install New software and
pass it that zip as an Archived p2 repo?

I downloaded them, unzipped them and added them as they are to the
new Eclipse installation. I started Eclipse with -clean option after that.

What would be the official way to install them? The download page
implies that I could just download them.

I tried that without success. I didn't get an error message, but it says
that "There are no categorized items". Then I unpacked the original zip
file and tried to install from a local repository, but I got the same
(empty list) result as via the archive.

Thanks for your help, Paul,

- Daniel

To make that clear: I did this experiment with a full clean Eclipse
again (I wanted to be sure that no remaining artifacts from my first
attempt could influence this negatively).

OK, it is a p2 repo (I checked). You have to uncheck the "Group items by
category" to see the features available. Then you can install them
correctly.

The download page is wrong (please open a bug) as you haven't been able
to unzip plugins into eclipse/plugins and have them work correctly since
3.4.x/p2.

Thanks for your tip, Paul - I can confirm the success of your described
procedure!
It seems to me that the effect of "Group items by category" (or at
least the decision to have this active per default" can be very
misleading for users of the Eclipse update tool, but that is clearly a
different problem.

I agree and so I added:
