clojure - lein run command raises exception -

once added 1 more namespace in (toy) project 1 exception raised after starting server:

lein run 

i copying below project.clj file.

(defproject compoj02 "0.1.0-snapshot"  :description "fixme: write description"  :url "http://example.com/fixme"  :license {:name "eclipse public license"  :url "http://www.eclipse.org/legal/epl-v10.html"}  :dependencies [[org.clojure/clojure "1.6.0"]              [ring "1.3.1"]              [compojure "1.2.1"]              [clout "2.0.0"]              [enlive "1.1.5"]              [org.clojure/data.csv "0.1.2"]              ;[org.clojure/data.csv]             ]  :main         compoj02.core) 

the error

   exception in thread "main" java.io.filenotfoundexception: not locate clojure/data/csv__init.class or clojure/data/csv.clj on classpath: , compiling:(compoj02/pompaq.clj:1:1)     @ clojure.lang.compiler.load(compiler.java:7142) 

the new namespace contains 1 simple function:

 (ns compoj02.pompaq    (:require [clojure.data.csv :as csv]              [clojure.data.io :as iov]))   (defn process-csv [file]     (with-open [in-file (iov/reader file)]       (doall          (csv/read-csv in-file)))) 

thanks reading!

ps. adding few details.i executed command lein deps. also, there chain of files: core.clj uses reference templates.clj , 1 uses reference pompaq.clj. when comment out declaration (:use compoj02.pompaq) used in namespace of templates.clj, able start application via lein run.

try lein deps make sure there. also, without -main function, command should =>

lein run -m compoj02.pompaq/process-csv file-arg-here
