title: Duplicate fragment name ERROR Jetty Maven Plugin
body: <p>I run the jetty-maven-plugin 8.0.0M2. Works fine after startup (mvn jetty:run) . If I change a source the plugin tries to hot deploy but gets stuck because of the following error</p>
  
  <pre><code> Duplicate fragment name: PrimeFaces for jar:file:/C:/path/to/project/webroot/WEB-INF/lib/primefaces-2.1.jar!/META-INF/web-fragment.xml and jar:file:/C:/path/to/project/webroot/WEB-INF/lib/primefaces-2.1.jar!/META-INF/web-fragment.xml
  </code></pre>
  
  <p>It worked fine with plugin version 7.2.0. I was upgrading because I needed el-api 2.2.
  Any ideas? Thanks</p>
