title: jhipster liquibase diff heroku
body: <p>I have create a very simple Jhipster app and deployed it to Heroku. Everything work fine so I added a new field to my very simple object and redeploy. I got the following error:</p>
  
  <pre><code>2016-09-07T12:32:49.375947+00:00 heroku[router]: at=info method=POST path="/api/tsts?cacheBuster=1473251569324" host=deplyjhip.herokuapp.com request_id=2b7190f7-0301-456d-87a9-7342640aad9d fwd="5.2.192.47" dyno=web.1 connect=0ms service=17ms status=500 bytes=532

  </code></pre>
  
  <p>I know what happens. When I redeploy using:</p>
  
  <pre><code>./gradlew -Pprod bootRepackage -x test
  heroku deploy:jar --jar build/libs/*war
  </code></pre>
  
  <p>it didn't run <code>./gradlew liquibaseDiff</code> </p>
  
  <p>How do I run liquibase diff and apply the changes on the heroku DB?</p>
