CIDER's version (0.12.0) does not match cider-nrepl's version (nil)

[naipmoro]

I am using the latest melpa-stable release of cider on a clean install
of emacs 24.5.1 on ubuntu 16.04.

When I cider-jack-in I get:
;; CIDER 0.12.0 (Seattle), nREPL 0.2.12
;; Clojure 1.7.0, Java 1.8.0_03-Ubuntu
WARNING: CIDER's version (0.12.0) does not match cider-nrepl's version (nil). Things will break!

So I figured I'd do this manually (following the docs):
(setq cider-inject-dependencies-at-jack-in nil)
then add
{:repl {:plugins [[cider/cider-nrepl "0.12.0"]]}} to ~/.lein/profiles.clj

No, that doesn't work either. Same warning.

But if I add the plugin to :user instead of :repl (which the docs say
I shouldn't do "as this way CIDER's middleware will always get loaded,
causing lein to start slower), I avoid the warning.

If the plugin is in :user, it doesn't matter whether cider-inject-dependencies-at-jack-in
is nil or not, the warning is gone.

I should also note that the same happens on windows 7-64 bit, but I don't really care.

[Malabarba]

Do you have any other plugin under the user profile?

[naipmoro]

Yes, here they are:
{:user {:plugins
[[lein-pprint "1.1.2"]
[lein-newnew "0.3.7"]
[lein-ancient "0.6.10"]
[lein-localrepo "0.5.3"]
[lein-grep "0.1.1"]
[lein-clojars "0.9.1"]
[lein-midje "3.2"]
[lein-difftest "2.0.0"]
[codox "0.9.4"]
[lein-gorilla "0.3.6"]
[com.jakemccrary/lein-test-refresh "0.14.0"]
[lein-collisions "0.1.4"]
[venantius/yagni "0.1.4"]
[cider/cider-nrepl "0.12.0"]]}}

[Malabarba]

Just exploring the possibilities here. Could you try removing your profiles.clj file completely?
Does cider-jack-in work automatically if you do that? (don't forget to leave cider-inject-dependencies-at-jack-in as t.)

[naipmoro]

Thank you for your help. The problem turned out to be the [lein-gorilla "0.3.6"] plugin.
Unfortunately that's the most up-to-date version. I now recall previous conflicts between
gorilla and cider.

[bbatsov]

They used to bundle some version of cider-nrepl with the gorilla plugin. Not sure what's the state of things today.

I'm seeing the same error message upon M-x cider-connect, but with different starting conditions: I'm using boot, and after upgrading cider in emacs to 0.12.0, and cider-nrepl to 0.12.0, have this in my profile.boot,

(deftask cider "CIDER profile"
  []
  (require 'boot.repl)
  (swap! @(resolve 'boot.repl/*default-dependencies*)
         concat '[[org.clojure/tools.nrepl "0.2.12"]
                  [cider/cider-nrepl "0.12.0"]
                  [refactor-nrepl "2.2.0"]])
  (swap! @(resolve 'boot.repl/*default-middleware*)
         concat '[cider.nrepl/cider-middleware
                  refactor-nrepl.middleware/wrap-refactor])
  identity)

Looking into refactor-nrepl it's pulling in cider-nrepl 0.10, could that be causing the problem? If so, will refactor-nrepl dependencies get bumped up anytime soon? Thanks!

[limist]

Update: i tried removing refactor-nrepl references in the above, and still get the same error message. Any suggestions for fixing this please? Thanks in advance.

[Malabarba]

How are you starting the repl? Are there any other tasks being used? What's the content of your *nrepl-messages ...* buffer immeditaly afterconecting?

[limist]

Hi @Malabarba,

• Starting the repl at the command line with boot dev-repl which is just boot repl and setting some app-specific environment vars.
• Other tasks: not that i know of.

...plus a lot more stuff, too long to put here (unless you think it would help).

[Malabarba]

Here's the problem:

nrepl  (dict 
        incremental  "3"
        major  "0"
        minor  "2"
        qualifier  ""
        version-string  "0.2.3")

nrepl version should be 0.2.12. It's possible one of your other tasks is conflicting here.

[Malabarba]

Or, better, just make sure you have [org.clojure/tools.nrepl "0.2.12" :scope "test"] in your project's dependencies.

[limist]

@Malabarba Thanks a lot for the quick help, doing boot show -d showed a library pulling in an old version of tools.nrepl that was shadowing the version specified in my profile.boot. All good for now ::-)

[echeran]

Fwiw, I had the same problem when using Leiningen. Running lein deps :tree showed that I had the recommended versions of org.clojure/tools.nrepl and cider/cider-nrepl, but I got these warnings:

Warning: cider-nrepl requires Clojure 1.7 or greater.
Warning: cider-nrepl will not be included in your project.

Bumping Clojure from 1.6.0 to 1.8.0 in my project.clj did the trick. I don't get those error messages from Cider after cider-jack-in anymore.

[Malabarba]

Thanks. Glad that the message helped you solve the problem.

[abhi18av]

Hi everyone,

Google led me here since I seem to be having a similar problem.

The message that my cider env throws is

CIDER's version (0.15.1-snapshot) does not match cider-nrepl's version (nil) 

Here are the relevant contents of my build.boot

NOTE : the error message is thrown once I include core.typed - otherwise, it does work fine.

          :dependencies   '[[org.clojure/clojure "1.9.0-alpha17"]
                            [adzerk/boot-test "RELEASE" :scope "test"]
                            ;; Matrix stuff
                            [net.mikera/core.matrix "0.60.3"]
                            [net.mikera/vectorz-clj "0.47.0"]

                            ;; Asynchronous stuff
                            [org.clojure/core.async "0.3.443"]

                            ;; Pattern matching in clojure
                            [org.clojure/core.match "0.3.0-alpha5"]



                            ;; Typed clojure
                            ;; TODO Creates an issue with cider's nrepl - probably transitive dependency
                            ;[org.clojure/core.typed "0.4.0"]

                            ;; TODO Middleware - might help to mitige the cider error caused by core.typed
                            ;[org.clojure/tools.nrepl "0.2.12" :scope "test"]




                            ;; MiniKanren
                            [org.clojure/core.logic "0.8.11"]

                            ;; Clojure reader in clojure
                            [org.clojure/tools.reader "1.0.5"]

                            ;; Shell library
                            [me.raynes/conch "0.8.0"]])

I've tried to remedy it with a ~/.boot/profile.boot

 (require 'boot.repl)
  
   (swap! boot.repl/*default-dependencies*
          concat '[[cider/cider-nrepl "0.15.1-SNAPSHOT"]])
  
   (swap! boot.repl/*default-middleware*
          conj 'cider.nrepl/cider-middleware)

Sadly, this doesn't seem to be working 😞

[jmckitrick]

I'm seeing the same thing using leiningen. When I remove my dependency on core.typed from the project, everything is fine. Otherwise, I see the same error from CIDER.

[bbatsov]

@jmckitrick Likely some bad interaction with core.typed that deserves a dedicated issue.
