21<h1>Maven Plug-in</h1>
22
23<p>
24 The JaCoCo <a href="http://maven.apache.org/">Maven</a> plug-in provides the
25 JaCoCo runtime <a href="#agent">agent</a> to your tests and allows basic
26 <a href="#report">report</a> creation.

29<p class="hint">
30 If you want to have line number information included in the coverage reports
31 or you want source code highlighting the class files of the test target must
32 be compiled with debug information.

36<h2>Prerequisites</h2>
37
38<p>
39 The JaCoCo Maven plug-in require
40</p>
41
42<ul>
43 <li>Maven 2.1.0 or higher and</li>
44 <li>Java 1.5 or higher (for both, the Maven runtime and the test executor).</li>
45</ul>
46
47<p>
48 The Maven plug-in can be included in your build with the following declaration:
49</p>
50
51<pre class="source lang-xml linenums">
52&lt;plugin&gt;
53 &lt;groupId&gt;org.jacoco&lt;/groupId&gt;
