First try, errors.

[Pink Bobsledder]

Hi I'd like to try out monger but I'm getting errors right out of the gate. Java (build 1.7.0_25-b17)

My project.clj:
(defproject pinkone "1.0.0-SNAPSHOT"
  :description "FIXME: write description"
  :url "http://pinkone.herokuapp.com"
  :license {:name "FIXME: choose"
            :url "http://example.com/FIXME"}
  :dependencies [[org.clojure/clojure "1.4.0"]
                 [com.cemerick/drawbridge "0.0.6"]
                 [com.novemberain/monger "1.7.0-beta1"]]
  :min-lein-version "2.0.0"
  :plugins [[environ/environ.lein "0.2.1"]]
  :hooks [environ.leiningen.hooks]
  :profiles {:production {:env {:production true}}})


My Error:
lein repl

Bye for now!

Any help would be great - this has me stumped for a couple days. I've tried other versions of monger 1.5 and 1.6 with the same error.

Pink Bobsledder:

Your have compiled code that was compiled against a different version of Clojure (likely something using

gen-class). Run lein clean. 

It is not a Monger problem. Monger does not use AOT compilation.

Thanks for the reply, I tried as you said but still have the same error.

However it got me thinking and I ended up starting a new project with 'lein new' and noticed the clojure version was 1.5.1 instead 1.4 in my previous project file. Upgrading clojure fixed the problem. Thanks again.
