Such a tool would be interesting and there has been some work in that direction in the Apache Felix area.  They are looking mostly at manifest generation.  We have some different requirements (e.g., about file injection, hand crafted manifests, ...) that have partially driven the current approach.  The short answer then is no, the topic has not come up.

Having said that, what is happening here is not rocket science.  Basically we are taking built thing and adding a few files to it and JAR'ing it up.  Your build could, for example, check out the Orbit stuff, build the lib from source, replace the Orbit supplied compiled classes with your compiled classes and then "build" the orbit bundle.  Yucky perhaps but it would indeed work.

Remember, Orbit is for the most part not changing how we are shipping things or really even how they are produced, just where they are managed/created.

There will be an interesting question as to how you ensure that the thing you built is the same as what we ship from Eclipse but that is not unique to or brought on by Orbit.

ICU is a different kettle of fish.  ICU comes to us as bundles so we really don't do anything at all to it.  For simplicity I think we decided to explode the ICU budnle into CVS projects and then reassemble but that is goofy.  All we really need to do is figure out how to stash the original ICU bundles in a safe spot and then materialize them on the appropriate download page.

In any event, ICU (and SSH) issues likely have to be taken up with the original projects.

Hope that helps
