define and use multiple repository caches ?

hi gradle-users and developers,

for myCompanys ant+ivy-based buildsystem we use 2
repository caches. One for the SNAPSHOT-artefacts and
one for all the other artefacts. we do this because we
want to be able to run the command 'cleanSnapshotCache'
that wipes out all the cached SNAPSHOT-artefacts (including
metadata) but leaves all other cached artefacts untouched.

we learned that we need to wipe out SnapshotCache in some
situations because otherwise we get into trouble with the resolving
of our SNAPSHOT-artefacts. (-> multiple chained snapshot-repositories,
useOrigin, caching of ivy-metadata)

my question is: can i define and use multiple artefact-caches
with gradle too ? how ?

here the ivysettings.xml where you can see,
how we define and use the caches for native ivy:

(note: we know 3 BuildEnvironments: 'development', 'integration', 'release'
and use different ivysettings (resolver-chains) for each of them. what you
see here is the ivysettings.xml for buildEnv = 'development')  

<ivysettings>

	<resolvers>

			<resolver ref="local"/>
			<resolver ref="shared"/>
			<resolver ref="snapshot"/>
			<resolver ref="released"/>

		</chain>
	</resolvers>
</ivysettings>

of course ... any way that makes the use of
multiple caches obsolete is preferred.

have a nice time
