Re: Cache root on tasks

[Xavier Hanin <xa...@gmail.com>]

Hi,

As we agreed in another e-mail in the old ivy-dev@i.a.o list, I've worked on
removing the ability to define the cache root on all Ivy ant tasks. I've
also removed this option from all engines options, so that now the cache
managers are defined at only one location:
- global in the settings for the resolution cache manager
- per dependency resolver for the repository cache manager

I still have some issues to fix to really give the flexibility to define one
repository cache manager per dependency resolver, but I think we are getting
close to IVY-399 resolution. One thing I'd still like to change in this area
besides the fix and improvement in flexibility is to make repository cache
managers responsible for managing the useOrigin flag. It would be much more
consistent IMO, and also more flexible, allowing to use one cache manager
for one resolver with useOrigin=true, and another cache manager for another
resolver with useOrigin=false.

This would mean removing useOrigin flag from the tasks, and adding it to the
cache settings (which will have to be improved to allow per resolver cache
manager). Since this would be a task backward incompatibility (which we tend
to avoid to ease 2.0 migration), I'd actually keep the useOrigin attribute
on the related tasks, but deprecate it, and only set a property from the
value set on the attribute. Then this property would be used as default
value for the useOrigin flag on the default repository cache manager (used
by all resolvers unless they specify another repository cache manager).

Do anybody see any problem with this approach?
