beginners emacs / clojure compiling error

Question

I'm going through clojure & emacs tutorial from clojure-doc.org, and when compiling the test as suggested, i get following output in emacs nrepl:

    clojure.lang.Compiler$CompilerException: java.lang.RuntimeException: Unable to resolve symbol: deftest in this context, compiling:(/home/jakov/dev/PROJECTS/clojure/test2/test/test2/core_test.clj:1)

To me, it seems like this line is crucial in the nrepl error output:

Caused by: java.lang.RuntimeException: Unable to resolve symbol: deftest in this context

Anyway, i am really a clojure & emacs noob, and I dont have much clue here. All the emacs slime clojure stuff is installed, leiningen2 is installed, java is oracle java 1.6, emacs is emacs 24, and when I run lein test in projects directory, it goes without errors.

Can anyone help me?

EDIT:

My core_test.clj file:

    (deftest pairs-of-values
   (let [args ["--server" "localhost" 
               "--port" "8080" 
               "--environment" "production"]]
      (is (= {:server "localhost"
              :port "8080"
              :environment "production"}
             (parse-args args)))))

My core.clj file:

(defn parse-args [args]
  {})

You really should have posted the code that's in your file. Do you have (ns core-test2 (:use clojure.test)) in there? — Marko Topolnik

I was following clojure-doc.org tutorial word-for-word.. I edited my question, anyway — tonino.j

The tutorial says "Replace the test that is there with the following". I think you replaced the entire contents of the file, instead of only the (deftest ...) part. So the part that you deleted, but shouldn't have, said (ns command-line-arguments.core-test (:use clojure.test command-line-arguments.core)) — Marko Topolnik

Yup. I deleted everything there and put that. I'll try to put that back. — tonino.j

(ns test.core-test (:use clojure.test test.core))

Actually, it was: (ns test.core-test (:use clojure.test test.core)) But, anyway, putting it back solved the issue. That was what leiningen put there by default.

What i got now when I compiled test file was:

FileNotFoundException Could not locate test/core__init.class or test/core.clj on classpath:   clojure.lang.RT.load (RT.java:432)

Seems like your directory structure is off now. You must have modified it away from what leiningen initially created for you. Do you have src/test/core.clj?

tonino.j Over a year ago

No, thats the point. I even tried it on brand newly created projects: lein new something, turn on emacs, turn on nrepl, open the core_test.clj, try to compile it without any change... and I get this. I tried going to root of the project, doing lein test and lein run in terminal.. It gives me some complaint or the test dont pass, but those are reasonable complaints, different than this.
