title: Install specific version of gradle
body: <p>I have to work on a project that runs with Gradle 2.2. </p>
  
  <p>I would like to install Gradle 2.2 in order to make the project build fine.  But I don't know how to do that, I only can install Gradle latest version. Is there a way to install a specific version of Gradle?</p>
  
  <p>I work on ubuntu 14.04 LTS.</p>
