RE: [p2-dev] Re: Error trying to partially p2.mirror EMF 2.5.0 updatesite

Thanks for the reply, Nick.  I tried to work around this by changing my
Ant task to:

    <p2.mirror verbose="true" ignoreErrors="true"
source="jar:file:C:/Temp/emf-xsd-Update-2.5.0.zip!/">
      <repository location="file:${final.p2.repo.dir}" compressed="true"
                   name="EMF repository" />
      <iu id="org.eclipse.xsd.feature.group" />
      <iu id="org.eclipse.emf.ecore.feature.group" /> 
      <iu id="org.eclipse.emf.common.feature.group"/>
    </p2.mirror>

But I still get the same error:

 [p2.mirror] Mirroring:
osgi.bundle,org.eclipse.emf.ecore,2.5.0.v200906151043 (Descriptor:
canonical: osgi.bundle,org.eclipse.emf.ecore,2.5.0.v200906151043)

I should explain what I am trying to do, I guess.  I have a plugin the
depends on the core XSD support in EMF and I just want to be able to
suck out the plugins/features I need.  My build is automated, so I was
hoping to also automate the creation of a partial EMF repository from
the large, all-in-one version, then pull down the tiny sub-repo that I
created as a dependency in my build (my build is currently set up to
consume/merge p2 repositories as binary dependencies).

I guess for now I could construct it manually with the Buckminster
Aggregator but I would really like to keep this automated so a
workaround in Ant would be the best solution for me.  Is there any way I
can simply inflate and unpack the current 'broken' repository?  I don't
mind the extra time to do this, provided I can do it simply (in Ant) and
without any other dependencies.

Thanks,
Mark.

Subject: [p2-dev] Re: Error trying to partially p2.mirror EMF 2.5.0
updatesite

The issue here is that the metadata is incomplete, and p2 (p2.director,
anyway - haven't tried w/ p2.mirror) only knows how to find foo.jar as
foo.jar.pack.gz in a jar:file:/path/to/repo.zip!/. If you omit the
jar:file: prefix or !/ suffix, or point at http://path/to/repo.zip, or
even unpack the zip as file:/path/to/repo.zip_, p2 can't find the packed
plugin jars.

(I've complained about this limitation but there's been no buy-in from
the p2 devs so far that this ought to be fixed, mostly I suspect because
there is a simple workaround and by fixing it they're encouraging
"broken" repos to be produced. Ours is "broken" because it saves disk
space and bandwidth; if we skip the packing step or include BOTH the
packed and unpacked jars in the zip, the file gets much larger.)

That said, I've been able to successfully mirror from a "broken" repo
zip like the EMF one using the Buckminster Aggregator.

See https://bugs.eclipse.org/bugs/show_bug.cgi?id=294832 for a quick way
to get a director app, then use that to install Buckminster, and from
there be able to do selective mirroring and even recategorization or
features. There's also a Buckminster Aggregator Editor which lest you
set up what to mirror graphically. Very cool, IMHO.
