title: Modify field annotation value dynamically
body: <p>Is is possible to change field annotation values at runtime?</p>
  
  <p>I can access the values, but can't find a way to change them.</p>
  
  <p>Access is possible with:</p>
  
  <pre><code>Article.class.declaredFields.find {it.name="annotatedField"}.declaredAnnotations
  </code></pre>
