clojure with mysql and java -

not sure why error when try code below execute query on mysql database clojure:

user=> (mysql.core/list-users)  classnotfoundexception mysql.core  java.net.urlclassloader$1.run (urlclassloader.java:366) 

here project.clj file

(defproject mysql "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 "1.5.1"]                     [org.clojure/java.jdbc "0.3.3"]                     [mysql/mysql-connector-java "5.1.25"]                     [postgresql/postgresql "8.4-702.jdbc4"]                     [org.xerial/sqlite-jdbc "3.7.2"]                     [java-jdbc/dsl "0.1.0"] ]) 

here core.clj file

(ns mysql.core  (:require [clojure.java.jdbc :as sql]))  (def db {:classname "com.mysql.jdbc.driver"      :subprotocol "mysql"      :subname "//localhost:3306/dummy"      :user "idf"      :password "pwd"})  (defn list-users []   (sql/with-connection db   (sql/with-query-results rows   ["select * user"]   (println rows)))) 

here works (the thing have deps correct without project file):

$ mysql -u root   mysql> create database clojure_test;   grant on clojure_test.* clojure_test@localhost identified "clojure_test”;   use clojure_test;   create table fruit (id int not null primary key auto_increment, name varchar(20),      appearance varchar(20), cost decimal(13,2));  lein repl user=> (require '[clojure.java.jdbc :as j]) user=> (def mysql-db {:subprotocol "mysql" :subname "//127.0.0.1:3306/clojure_test" :user "clojure_test" :password "clojure_test"}) user=> (j/insert! mysql-db :fruit {:name "apple" :appearance "rosy" :cost 24} {:name "orange" :appearance "round" :cost 49}) user=> (j/query mysql-db ["select * fruit appearance = ?" "rosy"] :row-fn :cost) 

it seems run code in repl, need change namespace , load file:

1, change repl's namespace (ns mysql.core)
2, run (load-file path-to-file)

edit:

another solution excute (use 'mysql.core) in repl, can run code.
