title: Hudson plugin warning
body: <p>I see the message in hudson console</p>
  
  <pre><code>WARNING: Faild to load hudson.plugins.groovy.GroovyTokenMacro
  java.lang.HoClassDefFoundError:    org/jenkinsci/plugin/tokenmacro/DataBoundTokenMacro .....

  <p>I have re downloaded  .hdi file and got same warning. I am not sure that it was before.</p>
  
  <p>How can I solve it? My hudson is in unsecured mode.</p>
