Description Grant Gayed CLA 2010-03-30 15:08:26 EDT 
Using I20100323-0800

- download and unzip eclipse
- download and unzip the SDK Examples download into eclipse's root directory
- verify that the *example* plugins were extracted into eclipse's plugins directory
- launch eclipse (use -clean if needed)
  -> note that the example plugins are not loaded

- possibly relevant, the following are in the Error log:

Unable to find feature.xml in directory: C:\eclipse\eclipse\features\org.eclipse.sdk.examples_3.2.100.v20090903-817eFSiFFGcVF2W_kSAS3NLb.jar

Unable to find feature.xml in directory: C:\eclipse\eclipse\features\org.eclipse.sdk.examples.source_3.2.100.v20090903.jar
Comment 1 Kim Moir CLA 2010-03-30 15:29:42 EDT 
You don't unzip, you install.  Did you try installing the examples from the zip?  The examples zip is a zipped p2 repository.
Comment 2 Grant Gayed CLA 2010-03-30 15:47:47 EDT 
I hadn't, but now that I try, it still isn't working for me.  My new steps:

- delete the previous eclipse install completely
- download and unzip eclipse
- download the SDK Examples
- start eclipse
- Help - Install New Software...
- Add... -> Archive... -> select the SDK Examples zip, OK
- the list just has one item: "There are no items available"
Comment 3 Kim Moir CLA 2010-03-30 15:58:01 EDT 
Deselect "Group items by category" when you try to install
Comment 4 Grant Gayed CLA 2010-03-30 16:10:45 EDT 
still no luck :(

I don't understand why the examples plugins aren't showing up as an installable feature in the UI.  Andrew, I'm going to attach the content.xml for the examples repo - can you take a look it and see if you have any ideas?

examples feature content.xml
Comment 8 Andrew Niefer CLA 2010-04-23 14:25:25 EDT 
The repository does not contain the "org.eclipse.sdk.examples.feature.group" IU.  The UI only shows features, in particular, it shows the feature.group IUs.

This seems to be the case for all the zipped repos (I checked cvs & pde).

This is happening because the <p2.remove.iu> task will remove an IU if it matches the "query" (here this is everything) and if there are no artifacts left on it after checking the "artifacts" filter.

In this case, the feature.group has no artifacts on it to start with and so gets removed.

Unfortunately I don't see any immediate way to fix this without some changes in the <iu/> elements or remove IU tasks.

New bundles fixed this issue today. Thanks Andrew!
