I've tried to download GEF 3.1.0 using the following options via the command
line (standalone) update manager:
-command install -featureId org.eclipse.gef -version 3.1.0 -from http://update.eclipse.org/updates/
The update site URL, ID, and version I obtained from the GEF feature.xml
file. What I'm doing is trying to utilize update manager functionality for
installing EMF and GEF during GMF's automated build process.
When I execute this command, I get the following error:
org.eclipse.core.runtime.CoreException[0]: org.eclipse.core.runtime.CoreException[0]:
java.io.IOException: Server returned HTTP response code: "404 Not Found"
for URL: http://update.eclipse.org/updates/plugins/org.eclipse.draw2d _3.1.0.jar.
After some investigation, it seems the update manager resolves the feature's
plug-ins to a default location based on the update site root, followed by
'/plugins/<plug-in name>.<version>.jar', if it does not find a reference
to the plug-in location in the site.xml file. For GEF features, it seems
the older site.xml references the 3.0 update locations using URLs prefixed
with '3.0/' (and, this seems to be a GEF exclusive). So, the feature itself
is matched, but plug-in references are resolved as in the above, without
'3.0/' in the path, and therefore causing the 404 Not Found error.
If I use http://update.eclipse.org/updates/3.0 for the -from argument, it
works as expected. Note that the update manager works fine through the GUI,
as I suspect it is using the ../3.0/site.xml file (or is able to resolve
the correct plug-in URLs by some other means).
So, not sure if I'm missing something here, or if it's an issue with the
update manager... but it seems if the URL in the feature.xml were to point
to http://update.eclipse.org/updates/3.0 all would be well.
Thanks,
Rich

We have a bug report open to sort this out. Thanks for your explanation
about what's happening behind the scenes, Rich. The updates don't work from
the GUI either. I think you're referring to discovery, which works fine.
The update URL only comes into play when you already have an older version
installed (and select the option to search for newer versoins of already
installed plugins).
