I have recently started out with clojure, and I am using leiningen to create a small project. I am having troubles in getting leiningen to behave with command line arguments. The following is my src/project/core.clj
(ns project.core
(:gen-class))
(defn -main [& args]
(println (apply str args)))
and my project.clj
(defproject project "1.0.0-SNAPSHOT"
:description "FIXME: write"
:main project.core
:dependencies [[org.clojure/clojure "1.2.0"]
[org.clojure/clojure-contrib "1.2.0"]])
Now when I run lein run arg1 arg2
, it gives me this error:
Exception in thread "main" java.lang.Exception: Unable to resolve symbol: arg1 in this context (NO_SOURCE_FILE:1)

However, if I do a lein uberjar
and then do java -jar project-1.0.0-SNAPSHOT-standalone.jar arg1 arg2
, I get the correct output.
arg1arg2
It isn't very comfortable to have to create the uberjar to run it every time while development, is there a better way?
