title: how to decrease build creation time with Maven
body: <p>I am using Maven in my project with 6 library projects. It take much time for maven to compile and create build. On my i-5 machine its taking 6-7 Mints</p>
  
  <pre><code> -------------------------------------------
   BUILD SUCCESS
   -------------------------------------------
   Total time: 8:29.254s
   Finished at: Tue Sep 24 13:25:45 PKT 2013
   Final Memory: 23M/223M
   -------------------------------------------
  </code></pre>
  
  <p>I wonder if there is way that allow maven to compile only project code/res each time instead of compiling each library again and again for the project. I am sure if so then build time will be much decrease</p>
  
  <p>Any one have idea? Or suggestions? </p>
