Hi all,
I would like to import the code of Bushel [1] into Ivy core.

I attended a few sessions about OSGi at the last ApacheCon US and I am
interested by this technology as well.
On the technical part.
Bushel implement some special Ivy resolver and version matching which
understand the different kind of OSGi dependency, and also understand the
repository descriptor OBR (OSGi Bundle Repository). So the import will make
those resolver part of Ivy core.
On the legal part.
The code has been developed under the ASL2 license and by only three
developpers: Alex Radeski, Jérôme Benois and me. I have contacted the two
others, they are joining me in this request and are willing to sign any
software grant paper necessary.
As the code will be imported into Ivy, the "Bushel" name will then disappear.
Ivy will then support some OSGi feature.
Deeper in the technical part.
As I explained here [2], Ivy cannot fulfill entirely the OSGi resolve specification. But
I have managed to make resolve work and I think it can fill some requirement like making
some transition from a ivy/maven based resolution mechanism to a pure OSGi based one. Or
the reverse. With that respect, we shouldn't lure Ivy users to say that Ivy support OSGi
and I suggest that we would flag at first it as "experimental". As users would
start to try it, we will see real world case appear, and then we would then advise of its
real state. This might sound quite pessimistic, but I find this feature exciting enough
to bring it into Ivy core.
A lot of innovations start that way, I see nothing wrong with this approach.
WDYT ?
Nicolas
