Clojure: High Performance JVM Programming

Creating a new project

Leiningen can help us create a new project using templates, there is a wide variety of templates available and you can build and distribute your own in Maven.

Some of the most common types of templates are:

• Creating a jar library (the default template)
• Creating a command-line app
• Creating a Clojure web app

Let's create a new Clojure command-line app and run it:

lein new app getting-started
cd getting-started
lein run
# Hello, world!

If you are familiar with Maven or Gradle, you can think of it as pom.xml or build.gradle respectively.
