title: Updating Vaadin project's GWT for Java 11
body: <p>I'm unable to build my maven project with vaadin and gwt components with <strong>JDK 11</strong>.</p>
  
  <p>I've updated the <strong>gwt-user</strong> and <strong>gwt-dev</strong> to latest (<strong>2.8.2</strong>) version.</p>
  
  <p>I'm using Vaadin7, tried with Vaadin8 also. Try to compile with the vaadin-maven-plugin.</p>
  
  <p>The output of my maven build : </p>
  
  <pre><code>[ERROR] Hint: Check that your module inherits 'com.google.gwt.core.Core' either directly or indirectly (most often by inheriting module 'com.google.gwt.user.User')
  </code></pre>
  
  <p>I saw related questions but nothing working for me.</p>
  
  <p>Can this stack work with Java 11 ? It works up to Java 8.</p>
  
  <p><strong>EDIT :</strong>
  To compile with JDK11, you'll need gwt-user, gwt-dev and vaadin-maven-plugin to 2.8.2. Then you'll need to upgrade Vaadin to Vaadin 8.9.1.</p>
