Leiningen Parent > Child > 3rd-Party Library Dependency Errors

Question

I'm using leiningen to develop 2 projects simultaneously (see Checkout Dependencies here). That's working and I've gotten it to a point where I want to deploy both libraries. Let's say they are lib-parent , which uses lib-child.

Now, I've deployed lib-child to clojars (lein deploy clojars). But if I now include lib-child as a project dependency in lib-parent, I can't load lib-child because one of it's dependencies (Datomic and it's use of com.google.common.cache.Cache) doesn't load. Running (require 'lib-child.plugin) at the repl will give me a ClassNotFoundException : com.google.common.cache.Cache.

Is this i) a general leiningen dependency issue or ii) an issue with Datomic not getting all of it's dependencies? I'm using [com.datomic/datomic-free "0.8.4143" :exclusions [org.slf4j/slf4j-nop org.slf4j/log4j-over-slf4j]].

Ok, fixed this. Removed all the :exclusions, in the Datomic declaration I used, in the lib-child project. Thanks to @hyPiRion on #leiningen @irc.freenode.org.
