Issue with org-babel-clojure evaluation returning all forms

Issue with org-babel-clojure evaluation returning all forms

I'm trying to set up babel for use with Clojure according to
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-clojure.html#org85bc1ec
and
I can evaluate code but when I evaluate a block with multiple forms in it
it outputs all of the form like so

#+begin_src clojure :results value
  (def small-map {:a 2 :b 4 :c 8})
  (:b small-map)
#+end_src

#+RESULTS:
: #'user/small-map4

I'm using cider for the back end as given in the tutorial and I'm not
getting any errors just unwanted input.

I don't think anything in my emacs config should effect this but I can post
if needed.

I'm also using org-plus-contrib as I the default org installation doesn't
allow me to evaluate clojure blocks, saying it can't find slime.

I've used the debugging tools to go through cb-clojure.el and found that
the nrepl-sync-request:eval result dictionary list the output of all of the
form in value without any separator so it may be something with cider, I'm
running the latest version from melpa-stable.

If any other information is needed, let me know and thanks in advance for
any help.

It is quite likely an issue due to changes in cider. Cider from melpa
gets a lot of updates and is a fast moving target.

IMO cider is not the best back end to use with org. You are probably
better off using inf-clojure. The cider back end has a lot of complexity
to support repl driven development which really complicates matters when
your just wanting to get clojure blocks evaluated and results back. The
inf-clojure back end is much simpler and undergoes less change, so is
more stable.

Personally, I'm not using this functionality in org. I found the
complexities of trying to get clojure blocks to work in this way was way
too high once you tried to do anything more than very simple statement
evaluation. I now use a more traditional literate programming approach
where I maintain the code in org files, but tangle the whole file to get
a clj/cljs file, which is what is loaded into the repl.
