title: SnakeYaml error: No writable property on class
body: <p>I've made a stupid mistake? I am new to yaml. Don't know why but my System does not see my variable called 'name'.</p>
  
  <p><a href="https://hastebin.com/gadoqeputi.pas" rel="nofollow noreferrer">Full error</a></p>
  
  <p>Error:</p>
  
  <pre><code>cannot create property=name for JavaBean=x.ModuleDescription@7ce6a65d
  </code></pre>
  
  <p>My class:</p>
  
  <pre><code>@Data
  @NoArgsConstructor
  @AllArgsConstructor
  public class ModuleDescription {
  
      private String name;
      private String main;
  
      private String version = "unknown";
      private String author = "unknown";
  
      @Setter
      private File file = null;
  }
  </code></pre>
  
  <p>I can see this field but my system does not. Hope that anyone got an idea. Thanks!</p>
