No :main namespace specified in project.clj

Question

I just started Web Development with Clojure but I am stuck with a real simple problem. I have :main myapp.core/foo in the project.clj

(defproject myapp "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"]]   ;; this will set foo as the main function   :main myapp.core/foo) 

but when I run lein I get this error:

C:\Users\a>lein run First No :main namespace specified in project.clj. C:\Users\a> 

What am I doing wrong?

Answer 1

First is an argument being passed to the main function of the namespace specified in C:\Users\a\project.clj. Did you want C:\Users\a\First\project.clj? If so, cd into that directory first.
