title: Intellij IDEA project build never completing
body: <p>I am trying to build my <em>Java</em> project, but the process never completes. The <strong>build</strong> progress spinner just spins forever as if it's stuck in an infinite loop.</p>
  
  <p>My code-base takes 15min to compile via the CI, but after 2 hours IDEA is still busy.</p>
  
  <p><strong>Why is my IntelliJ IDEA project build not completing?</strong></p>
  
  <p>I am not sure what additional info might be required to identify the problem; so please tell me and I'll gladly provide.</p>
  
  <p>IntelliJ IDEA 2017.3.2 (Community Edition) Build 173.4127.27</p>
