title: Incremental build in Jenkins
body: <p>I am using Jenkins 1.462 and maven version is 3.0.4.
  At Jenkins I enabled check-box "Incremental build - only build changed modules"</p>
  
  <p>I want to figure out 2 questions:</p>
  
  <ol>
  <li><p><strong>Whether incremental build is sufficient?</strong> 
  Here <a href="https://stackoverflow.com/questions/10318037/how-do-i-trigger-a-jenkins-build-of-a-single-module-in-a-multi-module-maven-buil">How do I trigger a Jenkins build of a single module in a multi-module Maven build from Subversion?</a> for example is stated that it doesn't work at 100%
  Here <a href="http://www.slideshare.net/andrewbayer/7-habits-of-highly-effective-jenkins-users" rel="nofollow noreferrer">http://www.slideshare.net/andrewbayer/7-habits-of-highly-effective-jenkins-users</a> at page 19 is stated that incremental builds are complementary to full builds, not replacements.</p></li>
  <li><p><strong>Whether <em>Incremental build - only build changed modules</em> is actually works as expected?</strong>
  What I mean by this? If I have modules A, B, X, C, D. X uses A and B, C use X, D use C and I make change in X module. Than I want to recompile modules X (itslef), C (that use X directly) and D (that is in transitive closure; D use C, that use C). </p></li>
  </ol>
  
  <p>Note: this is the only change that I did in order to enable incremental build.</p>
