title: Entities with @RequiredArgsConstructor error in IntelliJ IDE
body: <p>I'm trying to run sample Spring boot application and I'm facing problem with entities that are marked as @RequiredArgsConstructor on my IDE. I'm using latest intelliJ IDEA (14.1) over java 1.8. There's an error marked on IDE when I tried to initialize the entity with constructor arguments. </p>
  
  <p>E.g. It would be showing "cannot resolve symbol" for following line.</p>
  
  <pre><code>itemRepository.save(new Item("MacBook Pro"));
  </code></pre>
  
  <p>My entity would be as follows.   </p>
  
  <pre><code>@Entity
  @Data
  @RequiredArgsConstructor
  public class Item {
  
      private @Id @GeneratedValue Long id;
      private final String description;
  
      Item() {
          this.description = null;
      }
  }
  </code></pre>
  
  <p>Apart from IDE error project builds and runs properly. </p>
