Hi,
=20
I probably need my head realigned, but could you help me understand
something?
=20
I have the settings file below. And what I am doing is the following (or
so I think I am doing this):
=20
1. Cache all HTTP downloads into the "download-cache". This is
accomplished by specifying "download-cache" on the "url" based resolver.
When I run the build, I confirm this indeed does work as I anticipated.
Good.
=20
2. Define a "Local IVYREP" or sorts in the "ivy/ivyrep" directory. What
I anticipate using this for is for read-only retrievals in case I want
to test an upgrade of some library to a newer version, without impacting
anyone. (Problem, see below)
=20
3. Specify to IVY where to put its resolution cache and repository
cache.
=20
Concerns/Problems:
=20
1. The ivy publish commands seem to put the jars from my build in both
the "ivy/cache/repository" directory and the "ivy/ivyrep" directory.
Shuffling around copies of build artifacts is expensive.
=20
2. The "local" ivy/ivyrep directory should remain empty, or at least
that is my goal.
=20
What would help me is if I could understand what exact purpose
resolution caches, repository caches have, and what their relationship
is to a "local-resolver". Could someone explain this?
=20
And, if possible, could someone help me do the final tweaks to this
setup?
=20
Thanks in advance,

Bob
