Adding datomic-free to project fails cider-nrepl


#1

I’m using Duct/Integrant and want to play with Datomic first as an in-memory database. When I add [com.datomic/datomic-free “0.9.5697”] to my project.clj file, I get the error shown below and cannot connect to cider-nrepl. Can someone give me a hint as to what might be causing this and in which user groups I should ask for help, duct, cider, or piggieback?

error in process sentinel: Could not start nREPL server: Error loading cemerick.piggieback: java.lang.NoSuchMethodError: com.google.common.base.Preconditions.checkState(ZLjava/lang/String;Ljava/lang/Object;)V, compiling:(closure.clj:100:1)

I was able to fix the problem by adding the following exclusion.
[com.datomic/datomic-free “0.9.5697”
:exclusions [com.google.guava/guava]]
