title: Gradle application plugin with multiple main classes
body: <p>I'm using the gradle 'application' plugin to start my application. This works well.
  Now I want to add the option to start a different main class in the same project. Can I change the plugin's configuration to allow that?</p>
  
  <pre><code>apply plugin: 'application'
  
  mainClassName = "net.worcade.my.MainClass"
  </code></pre>
