| All of the projects except the PAR project have Maven POM files for building. In this step |
| an initial POM file for the PAR is created. |
| </p><p> |
| Using a text editor create a file called <code class="filename">$GREENPAGES_HOME/start/greenpages/pom.xml</code>. |
| Open this file and add the following skeleton to it: |

| ensuring that the version numbers are consistent |
| (for example, <code class="literal">2.3.0.RELEASE</code> might be <code class="literal">2.3.0</code> |
| depending on which version of <code class="literal">greenpages</code> being developed). |
| </p><p> |
| This skeleton defines a basic configuration with a parent POM. Notice that the <code class="literal">packaging</code> |
| type is <code class="literal">par</code>. After this file is created execute the following command from the |
| <code class="filename">$GREENPAGES_HOME/start/greenpages</code> directory. |
| </p><pre class="programlisting">mvn clean package</pre><p> |
| </p><p> |
| This command returns an error indicating that Maven does not know how to build a PAR: |
| </p><pre class="programlisting">[INFO] ------------------------------------------------------------------------ |
