Environment & Version information

CIDER version information

0.12.0-SNAPSHOT (master)

Lein/Boot version

boot 2.5.5

Emacs version

24.5

Operating system

Ubuntu Linux 14.10

The exception involves fipp and it is here.

My cider task is:

(deftask cider
  "Add CIDER support:
   https://github.com/boot-clj/boot/wiki/Cider-REPL"
  []
  (require 'boot.repl)
  (swap! boot.repl/*default-dependencies*
         conj '[cider/cider-nrepl "0.12.0-SNAPSHOT"])
  (swap! boot.repl/*default-middleware*
         conj 'cider.nrepl/cider-middleware)
  identity)

Removing the cider, removing the middleware, successfully launches the repl.
