title: Append content from file using Email Ext Jenkins plugin
body: <p>I have been modifying the default groovy template that the Email Ext plugin supplies. </p>
  
  <p>Firstly, I had to modify the JUnitTestResult and need to format it accordingly to my need. I found in the <code>it.JUnitTestResult</code>, <code>it</code> is a reference to the <code>ScriptContentBuildWrapper</code> class. And then I was able to format the JUnitTestResult according to my need.</p>
  
  <p>Now I am facing a second difficulty: </p>
  
  <ul>
  <li>Along with those contents, I need to append more content from a file that resides in the job workspace. How to access the files that reside in the workspace directory.</li>
  </ul>
  
  <p>I would be interested to know how I can access the build context object. Whats the java class name and things like that.</p>
