I've felt that we need to migrate our choice of IoC (plexus) towards a
better documented and better supported container (I'm leaning towards
Spring)
I also recognize that this kind of change can't be done quickly or in a
big-bang approach.
I've started an assessment of the plexus usage within Archiva and have
planned out a first draft on what we can do to change that usage.
There are plenty of plexus components that need to be migrated before we
can make the change to use a container such as spring. There's also the
whole Redback package that would need to be migrated as well.
So here's my first draft.
If there is interest, we can start to plan, schedule, and do the changes
in small increments.
This should probably live as a document in the wiki, but for now I think
we can discuss this in the mailing list.
