Re: [babel-dev] Babel Galileo Update Site 
Hi Kit,
It sounds like you tried out the p2 publisher in this case, is that right? (ie manually, not through Babel.) If so, you need to run the XSL that Antoine mentioned. See the attachment to https://bugs.eclipse.org/bugs/show_bug.cgi?id=256430.
If that still leads to dependency problems, we should reopen bug 256430, since it sounds like the same problem.

I spent some time in the past few days to understand the p2 publisher
problem. I noticed a few things.

Ian agreed in https://bugs.eclipse.org/bugs/show_bug.cgi?id=274025#c36
that there is still a problem with the p2 publisher. The p2 publisher
does not scale when there are many many features and plugins like our
case with the Babel language packs.

However, my understanding of the p2 publisher is that it's just a tool
for converting a number of different resources (e.g. update site,
features and bundles, or product) into a p2 repository. If we have all
the time in the world, and the patience, the p2 publisher will
eventually finish (in about 20 hours). I tried connecting to the newly
generated p2 repository and update my Eclipse SDK 3.5 RC4 for Win32. The
update failed with the following message:

!MESSAGE Missing requirement: org.eclipse.core.net.linux.x86 Pseudo
Translations NLS Support 3.5.0.v20090531043401
(org.eclipse.core.net.linux.x86.nl_en_AA 3.5.0.v20090531043401) requires
'bundle org.eclipse.core.net.linux.x86 0.0.0' but it could not be found

Our update site is including all the plugins we built using all the
translations we have in the database. That includes plugins like:

org.eclipse.core.net.linux.x86.nl_<locale>
org.eclipse.core.net.win32.x86.nl_<locale>
org.eclipse.compare.tests.nl_<locale>
org.eclipse.pde.build.tests.nl_<locale>

The problem is, if we are running Eclipse on Win32, the
*org.eclipse.core.net.linux.x86* plugin is not installed. If we are
running Eclipse on Linux, the *org.eclipse.core.net.win32.x86* plugin is
not installed. Also, the **.tests *plugins are only available from CVS
source repository but not included in the Eclipse downloadable binaries.

Update Manager is just reading the update site info and p2 repository,
looking for the required Fragment-Host bundle, and it's true that it
could not be found.

Therefore, I think the fundamental problem may be the way we build our
update site. I don't have much experience in building update site. I
wonder if there is an option to tell Update Manager to install a plugin
*"only if the Fragment-Host bundle is available"*. Otherwise, just skip
the updating the plugin.
