My uberjar build is failing when I remove:

:dependencies [[ring/ring-mock "0.4.0"]]

…from uberjar profile. Any idea why? I only have that requirement listed in my :dev profile in profiles.clj.

try running lein deps :tree , look for conflicts between "jackson" related libraries a common problem is that jackson releases wholly incompatible versions, and depending on what's in your deps, different transitive deps pull different versions of jackson libraries, so a random change in the deps list breaks unrelated deps

noisesmith16:06:46

a common approach is to use clojure.data.json instead of cheshire, as it doesn't require jackson, so removes a source of breakage

This is the only reference I have in the tree to “cheshire” and “jackson”:

[ring/ring-mock "0.4.0" :scope "test"]
   [cheshire "5.8.1"]
     [com.fasterxml.jackson.core/jackson-core "2.9.6"]
     [com.fasterxml.jackson.dataformat/jackson-dataformat-cbor "2.9.6"]
     [com.fasterxml.jackson.dataformat/jackson-dataformat-smile "2.9.6"]
     [tigris "0.1.1"]

I don’t have cheshire as one of my direct dependencies.
