title: GroovyDoc in Gradle not working
body: <p>I am trying to generate groovydocs in gradle script using command <code>gradle groovydoc</code>. I can see the command executed successfully as below:</p>
  
  <pre><code>Dynamic properties are deprecated: http://gradle.org/docs/current/dsl/org.gradle.api.plugins.ExtraPropertiesExtension.html
  :compileJava UP-TO-DATE
  :compileGroovy UP-TO-DATE
  :processResources UP-TO-DATE
  :classes UP-TO-DATE
  :groovydoc UP-TO-DATE
  
  BUILD SUCCESSFUL
  </code></pre>
  
  <p>But I don't see any API generated in the file system. What am I missing here?</p>
