title: Applying plugin in init.gradle
body: <p>I have a very simple gradle plugin I've developed.  I've been using it without issue in an example project, like so</p>
  <p><code>build.gradle</code></p>
  <pre><code>apply plugin: &quot;com.imrichardcole.simpleplugin&quot;
  </code></pre>
  <p><code>settings.gradle</code></p>
  <pre><code>buildscript {
      dependencies {
          classpath files(&quot;plugins/simple_plugin-0.0.11.jar&quot;)
      }
  }
  </code></pre>
  <p>Which works as expected.  I'm now looking to move this from the projects <code>build.gradle</code> into <code>init.gradle</code> under <code>~/.gradle/</code> so that it can be applied to all gradle projects I might ever work on.</p>
  <p>However when moving the above snippets into the <code>init.gradle</code> file, I get the error:</p>
  <pre><code>Plugin with id 'com.imrichardcole.simpleplugin' not found
  </code></pre>
  <p>Why does this work when it's inside <code>build.gradle</code> or <code>settings.gradle</code> but not <code>init.gradle</code>?</p>
