Launch a plain clojure repl according to project.clj without leiningen (most of the time). This version supports CIDER and clj-refactor

#! /bin/bash
# launch a clojure plain repl but with options and classpath matching project.clj
# Except when project.clj changes (and on first launch), lein is not called.
