How to pass a list of IUs to org.eclipse.equinox.p2.artifact.repository.mirrorApplication? (was Re: [p2-dev] p2 metadata generator does not generate artifact entries for packed jars if unpacked jar not present too)

Is there a -iu flag equivalent to <p2.mirror><iu></p2.mirror>? If I want to explicitly set a list of IUs, how can I do so dynamically? I would prefer to not have to iterate through a list of features pulled from the contents of the zip (which I can do easily), then have to GENERATE ant code and run that as a separate downstream task.

Simpler would be to be able to pass a list of IUs to org.eclipse.equinox.p2.artifact.repository.mirrorApplication, like this:

-IU org.foo.feature.group,org.bar.feature.group,org.baz.feature.group,...

rather than

<iu id="org.foo.feature.group" />
<iu id="org.bar.feature.group" />
<iu id="org.baz.feature.group" />

(Problem is to do a mirroring operation I need to include associate sites or p2 will complain it can't find dependencies; when I include the associate sites but do not list the IUs I want, p2.mirror will mirror the ENTIRE site. So, if I want to merge two update site zips and list galileo site as an assoc site to resolve deps, I end up with a mirror of all three sites, not just the two zips.)

Or, is there a way to pass a collection, list, array, or fileset to <p2.mirror> ?

Apologies if this is a dumb question, but the help.eclipse.org docs fail to mention how to tell the mirrorApplication which IU(s) to mirror.

No. Neither the metadata generator nor the publisher supports the generation of metadata from packed jar. This would require the generation process to unpack the jar and process them.

If the original update site (the one for which you have the pack'ed jars) already contains metadata, reuse the initial repository as a starting point to generate the new metadata (see -append flag).

The mirroring tool would do that: http://help.eclipse.org/galileo/index.jsp?topic=/org.eclipse.platform.doc.isv/guide/p2_mirror.html
