title: How I can speed up the build process using Maven
body: <p>I am using Maven as build tool. Presently I am building using this command.</p>
  
  <p><em>Right click on the project</em> > <em>Maven clean</em>.</p>
  
  <p>After this:</p>
  
  <p><em>Right click on the project</em> > <em>Maven install</em></p>
  
  <p>It is taking 3 minutes for me. Is there any way to speed up my process?</p>
  
  <p>I have already looked at <a href="https://stackoverflow.com/questions/161698/how-can-i-speed-up-my-maven2-build">this</a>. But I did not understand this. Can any one hep me?</p>
