+1 for me. There is a chance I'm going to use OSGi @ work, so this could be a 
good test case :-)

I've noticed the code is not JDK 1.4 compatible, but I guess it won't be a 
problem to downgrade it?
Or maybe we should drop the JDK 1.4 requirement for Ivy, but I would rather not 
do that as long as Ant is also 1.4 compatible.

Subject: Import Bushel into Ivy

Hi all,

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

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 exiting enough to 
bring it into Ivy core.



WDYT ?

Nicolas
