We have both a snapshot and release repositories in Artifactory. All we have to
do is add "-SNAPSHOT" to the end of the revision and we get the snapshot and
not the release. Maven does not guarantee you can select which snapshot you
want. In Maven 3, you can only get the last one.
Here's our ivysettings-pulbic.xml:
<ivysettings>
<resolvers>
<ibiblio name="public"
m2compatible="true"
checkmodified="true"
root="http://buildl01.tcprod.local/artifactory/libs-release"; />
</resolvers>
</ivysettings>
We setup Artifactory so that libs-release is actually a virtual repository
which includes our local release and snapshot repos (plus a bunch of public
repos).
