error in process sentinel: Could not start nREPL server

Question

attempting to start cider with Mx cider-jack-in with clojure project file in current buffer on Emacs 24.4.1. I get error in process sentinel: Could not start nREPL server

does nREPL need separate installation...is this an error anyone else is experiencing with 24.4.1?

messages buffer: Starting nREPL server via /usr/bin/lein update-in :dependencies conj \\[org.clojure/tools.nre\\ |11:56:07 hello: |pl\\ \\"0.2.12\\"\\] -- update-in :plugins conj \\[cider/cider-nrepl\\ \\"0.14.0-SNAPSHOT\\"\\] -- re\\ |11:56:07 hello: |pl :headless... |11:56:08 hello: |error in process sentinel: nrepl-server-sentinel: Could not start nREPL server: ^[[?25h^[[0G\\

Answer 1

Simple matter of having the correct versions of lein and clojure(script) and rtfm on https://github.com/clojure-emacs/cider-nrepl . To solve this I had to upgrade clojure to 1.7+ and lein to 2.5.2 . After these upgrades everything worked nicely.
