title: How do you exclude a transitive project dependency in gradle
body: <p>given</p>
  
  <pre><code>dependencies {
     compile project(':subproject') {
          transitive = false
     }
  }
  </code></pre>
  
  <p>This does not work properly in gradle 1.3. (i.e. all dependencies are included from the subproject)</p>
  
  <p>Is this a bug or is there a different syntax for excluding project dependencies?</p>
