I've made a small amount of headway on this issue. It seems that there
are two schemas used for creating OBRs (described here
<http://felix.apache.org/site/apache-felix-osgi-bundle-repository.html#ApacheFelixOSGiBundleRepository-OBRRepositoryFile>).
The repository file I created using the repoindex tool (a.k.a bindex,
here <https://github.com/osgi/bindex>), seems to have the form defined
by the OSGi spec and not the Felix OBR form. In looking at the source
code where the exception occurs (I have a copy of the source but I was
unable to find a link to it now; it seems surprisingly difficult to
find) it seems that the repository parser is looking for a tag called
"require" and not "requirement" which is what my repository XML file
has. So my question is "how do I get the bundlerepository code to parse
my OSGi repository file?" Or, I could also solve this problem by
creating a repository file in the OBR format but I'm not sure how to do
that.
I should also probably state my main goal: I'm trying to update a remote
OBR XML file with the data for a new bundle resource. I know the Maven
Bundle Plugin does this but I'm actually trying to write a similar
plugin for Leiningen - Clojure's build tool.
Any help with this would be greatly appreciated.
