Update the project

We need to specify how Leiningen builds our project in a little more detail. We also need to tell Heroku how we want our application to run.

Configure the Leiningen Build

Edit the project.clj file and add the following lines, usually after the dependencies declarations

:min-lein-version "2.0.0"
:uberjar-name "todo-list.jar"

The update project file should look as follows

(defproject todo-list "0.1.0-SNAPSHOT"
  :description "A simple webapp using Ring"
  :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 "1.4.0-beta2"]
                 [compojure "1.3.4"]]
  :main todo-list.core
  :min-lein-version "2.0.0"
  :uberjar-name "todo-list.jar"
  :profiles {:dev
              {:main todo-list.core/-dev-main}})
