title: Maven PDF doesn't include site information
body: <p>Using:</p>
  
  <ul>
  <li>Maven 3.2.3</li>
  <li>Java 1.8</li>
  </ul>
  
  <p>I generated the site by using:</p>
  
  <pre><code>mvn site
  </code></pre>
  
  <p>I then wanted to generate the PDF from this generated site (which according to the <a href="http://maven.apache.org/plugins/maven-pdf-plugin/usage.html" rel="nofollow">PDF Plugin Usage</a>, it uses the site documents). I just ran the command:</p>
  
  <pre><code>mvn pdf:pdf
  </code></pre>
  
  <p>Maven does generate a PDF, but all it does is show the Project Name, version, "Project Documentation" and a TOC that doesn't go anywhere. All the site information is missing.</p>
  
  <p>Do I need to include something in the POM or something else to get this to work? I appreciate the help!</p>
  
  <p><strong>UPDATE</strong></p>
  
  <p>As per a comment below, I have tried using a <code>pdf.xml</code>, which seems to be getting me closer to the output I am looking for.</p>
  
  <p>The <strong>pdf.xml</strong> looks like:</p>
  
  <pre><code>&lt;document xmlns="http://maven.apache.org/DOCUMENT/1.0.1"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="http://maven.apache.org/DOCUMENT/1.0.1
            http://maven.apache.org/xsd/document-1.0.1.xsd"
            outputName="MyProject"&gt;
  
      &lt;meta&gt;
          &lt;title&gt;My Project&lt;/title&gt;
          &lt;author&gt;IT Department&lt;/author&gt;
      &lt;/meta&gt;
  
      &lt;toc name="Table of Contents"&gt;
          &lt;item name="Introduction" ref="index.html"/&gt;
          &lt;item name="Goals" ref="project-info.html"/&gt;
          &lt;item name="Dependencies" ref="dependencies.html"/&gt;
          &lt;item name="Dependency Tree" ref="dependency-tree.html"/&gt;
          &lt;item name="Team" ref="team-list.html"/&gt;
      &lt;/toc&gt;
  
      &lt;cover&gt;
          &lt;coverTitle&gt;${project.name}&lt;/coverTitle&gt;
          &lt;coverSubTitle&gt;v. ${project.version}&lt;/coverSubTitle&gt;
          &lt;coverType&gt;User Guide&lt;/coverType&gt;
          &lt;projectName&gt;${project.name}&lt;/projectName&gt;
          &lt;projectLogo&gt;http://somesite.com/logo.jpg&lt;/projectLogo&gt;
          &lt;companyName&gt;Google&lt;/companyName&gt;
          &lt;companyLogo&gt;http://google.com/logo.gif&lt;/companyLogo&gt;
      &lt;/cover&gt;
  &lt;/document&gt;
  </code></pre>
  
  <p>The HTML files I refer to are in <code>/src/site</code>. They are then also put into <code>/target/pdf/site.tmp</code> folder.</p>
  
  <p>Maven gives the follow output, that has issues:</p>

  <p>No matter what I try, I cannot resolve the <strong>Unresolved id reference</strong> issue. the PDF generates and the TOC is shown, but no numbers to the right and no other pages are shown.</p>
