Leiningen Build tool

Leiningen (pronounced line-ing-en) is a very powerful build automation tool. With it you can:

  • Create Clojure Projects
  • Define and manage dependencies
  • Run an interactive Clojure environment (REPL)
  • etc.

Install Leiningen and test it works

Download the install script from leiningen.org and run the Leiningen script in a terminal

On Linux and MacOSX, make the script executable first

chmod a+x lein
./lein

hint I create a ~/bin directory and add it to my operating system execution path ($PATH), placing the lein script in ~/bin so I can call it from anywhere on the filesystem.

Test that Leiningen is installed with the following command

lein version

Output should look similar to:

Leiningen 2.4.3 on Java 1.7.0_45 Java HotSpot(TM) 64-Bit Server VM
