title: Gradle new plugin installation
body: <p>What should I do to install a plugin into gradle so I can use it in the future builds.</p>
  
  <p>I want to use rpm plugin here: <a href="https://github.com/TrigonicSolutions/gradle-rpm-plugin" rel="nofollow">https://github.com/TrigonicSolutions/gradle-rpm-plugin</a></p>
  
  <p>I tried downloading the project and copying the jar that's there in the %GRADLE_HOME%/lib/plugins, but it doesn't look like it works since </p>
  
  <pre><code>apply plugin: 'rpm' 
  </code></pre>
  
  <p>fails.</p>
  
  <p>This should probably be easy, but I don't see it in docs or can't really find how to do it. Do I need to run some task to put the jar in the repository of plugins? Any info would be appreciated.</p>
