cider-nrepl issue

[Philippe Guillebert]

Hi

I'm trying the clojure-android stack and so far it's been amazing...and frustrating.

My stack :

Emacs 24.4 with emacs-live (perfectly vanilla) includes CIDER 0.8.1
lein-droid "0.4.0-alpha2"

my project contains :

:dependencies [[org.clojure-android/clojure "1.7.0-alpha6" :use-resources true]
                 [neko/neko "3.2.0"]]

In my profiles.clj :

 :android-user {;; :dependencies [ [cider/cider-nrepl "0.8.2"] ]
                :plugins [
                          [lein-droid "0.4.0-alpha2" :exclusions [org.clojure/clojure]]
                          [cider/cider-nrepl "0.8.1"]
                          ]
                :android {:aot-exclude-ns ["cider.nrepl.middleware.util.java.parser"
                                           "cider.nrepl" "cider-nrepl.plugin"]}}


Everything works well, I can connect to the REPL of my app by connecting to localhost 9999 ;

But, CIDER complains it cannot find cider-nrepl :

; CIDER 0.8.1 (Java 0, Clojure 1.7.0, nREPL nil)
WARNING: The following required nREPL ops are not supported:

Please, install (or update) cider-nrepl 0.8.1 and restart CIDER

And a stack is thrown :

java.util.concurrent.ExecutionException: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.String[] java.lang.String.split(java.lang.String)' on a null object reference

    clojure.main$repl$read_eval_print__7042$fn__7045.invoke (main.clj:244)



The main issue is emacs is unusable as it tries to autocomplete stuff and freezes completely for several seconds every time I type something. So frustrating !

1) Is cider-nrepl expected to work on the device ?
2) if not, do you know how to make emacs usable (maybe disable advanced cider stuff) ?

Thank you

Philippe

Someone on IRC had this problem before. Can you try building and running a sample project (from here: https://github.com/clojure-android/lein-droid/tree/master/sample)?

CIDER is expected to completely work on Android (except for cider debugger, this part is not supported yet).
