leiningen with multiple main classes

Question

I\'d like to have two main classes (or more) with leiningen, and then be able to choose which one at the java command line. For example I have:

(ns abc (:gen-cla         


        

Answer 1

This works at least with leiningen 2.0+

(defproject my-jar "0.0.1"
 :description "test"
 :dependencies [
 ]
 :profiles {:main-a {:main abc}
           {:main-b {:main def}}
 :aliases {"main-a" ["with-profile" "main-a" "run"]
           "main-b" ["with-profile" "main-b" "run"]})

Then you can run each main like so:

lein main-a
lein main-b

Which expands to this:

lein with-profile main-a run
lein with-profile main-b run

I'm using this in one of my projects and it works perfectly.
