title: Gradle build only one module
body: <p>I have a multiple module gradle build. I want to execute targets for one module using root. 
  Ex : </p>
  
  <pre><code>gradle build -Pmodule=ABC
  gradle jar -Pmodule=ABC
  gradle test -Pmodule=ABC
  gradle compileJava -Pmodule=ABC
  gradle customTask -Pmodule=ABC
  etc.
  </code></pre>
  
  <p>So every target can be run from root specifying the module.
  Is there a simple way to do this?</p>
  
  <p>Thanks !</p>
