Weird error in cider-jack-in

Question

I created a clojure project using lein new , started GNU Emacs , opened the file core.clj and when I tried to jack-in with cider-jack-in It blows off:

Making nrepl-create-client-buffer-function local to *nrepl-server clojure-noob* while let-bound!
Making nrepl-use-this-as-repl-buffer local to *nrepl-server clojure-noob* while let-bound!
Starting nREPL server via lein repl :headless...
nREPL server started on 37124
nREPL: Establishing direct connection to localhost:37124 ...
nREPL: Direct connection established
error in process filter: cider-repl-set-initial-ns: Symbol's value as variable is void: ns
error in process filter: Symbol's value as variable is void: ns

and then (obviously) nothing happens

My core.clj file is:

(ns clojure-noob.core
  (:gen-class))

(defn -main
  "I don't do a whole lot ... yet."
  [& args]
  (println "¡Soy una tetera pequeña y fuerte!"))

As you can see, nothing fancy or anything... (it runs with lein run )

My .lein/profiles.clj is pretty simple:

{:user {:plugins [[cider/cider-nrepl "0.10.0-SNAPSHOT"]]}}

And my cider version is:

CIDER 0.10.0snapshot (package: 20150830.328)

as reported by Mx cider-version

I am new in Clojure , btw...

Could you help me?

Answer 1

It's a bug in the latest version of cider (already fixed: http://bit.ly/1UfNgE9 ).

As for now, you can apply this change manually on your local cider installation or just wait for fix publishing.
