title: Class not enhanced error
body: <p>I've been trying to fix this error:</p>
  
  <blockquote>
    <p>{"exception":"Persistent class \"Class org.myapp.model.Account does
    not seem to have been enhanced. You may want to rerun the enhancer and
    check for errors in the output.\" has no table in the database, but
    the operation requires it. Please check the specification of the
    MetaData for this class."}</p>
  </blockquote>
  
  <p>I've tried cleaning up the project </p>
  
  <p>This is the <strong>Entity</strong> that I'm trying to persist:</p>
  
  <pre><code>@SuppressWarnings("serial")
  @PersistenceCapable(identityType = IdentityType.APPLICATION)
  public class Account implements Serializable {
      @PrimaryKey
      @Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
      private Long id;
      @Persistent
      private String username;
      @Persistent
      private String password;
  
      public Account() {
  
      }
      // Code omitted
  }
  </code></pre>
  
  <p>How can I fix this issue?</p>
