leiningen midje tests not working in Intellij

Consider the following (minimal) leiningen project

./project.clj:

(defproject repro "0.1.0-SNAPSHOT"
  :dependencies [[org.clojure/clojure "1.5.1"]
                 [midje               "1.5.1"]])

./repro/src/repro/core.clj:

(ns repro.core)

./repro/test/repro/core_test.clj:

(ns repro.core-test
  (:require [repro.core  :refer :all]
            [midje.sweet :refer :all]))

(facts "about numbers"
       (fact "trivial"
         1 => 1) )

If I have the leiningen midje plugin installed, this runs at the command prompt as follows:

lein clean
lein midje
~~> All checks (1) succeeded.

However, if I import the leiningen project into Intellij 12.1.5 Community Edition, I get a fat stack trace:

Looks like La Clojure + Intellij can't find some of midje's prerequisites, which is odd, because La Clojure is running classpaths out of the leiningen .m2 directory.

I've looked for a midje plugin for Intellij, but no luck so far.

I need this because although I am happy to use just emacs + leiningen, my team wants Intellij.
