title: IntelliJ IDEA generating serialVersionUID
body: <p>How do generate this value in IntelliJ IDEA?</p>
  
  <p>I go to <em>Settings</em> -> <em>Errors</em> -> <em>Serialization issues</em> -> Serializable class without ‘serialVersionUID’, but it still doesn't show me the warning. My class PKladrBuilding parent implements <em>interface Serializable</em>.</p>
  
  <p>Part of the code:</p>
  
  <pre><code>public class PKladrBuilding extends PRQObject
  
  public abstract class PRQObject extends PObject
  
  public abstract class PObject implements Serializable
  </code></pre>
