title: Does Leiningen require a JDK/JRE?
body: <p>I've tried to install Leiningen according to the official installation instructions. When running <code>lein repl</code> I get the following error message:</p>
  
  <pre><code>/usr/local/bin/lein: line 315: java: command not found
  </code></pre>
  
  <p>This leads me to believe that Leiningen requires a JDK/JRE to actually run but there is no mention of it in the docs. So, do I first need to install a JDK/JRE?</p>
