title: netbeans can't find dot in path
body: <p>I have a maven project. I am using umlgraph to generate a graph. I have installed graphviz and is present in path. </p>
  
  <p>But when i try to run mvn javadoc:javadoc, netbeans complains</p>
  
  <pre><code>java.io.IOException: Cannot run program "dot":
  </code></pre>
  
  <p>Is there a way i can specify the path of dot.exe to maven or to netbeans. </p>
  
  <p>I did not install netbeans. its a OS independent zip file. I looked into netbeans.conf but not sure how to specify the path to dot.exe over there. </p>
