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.

Using a text editor create a file called $GREENPAGES_HOME/start/greenpages/pom.xml. Open this file and add the following skeleton to it.

<?xml version="1.0" encoding="UTF-8"?>
<project
    xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

  <parent>
    <groupId>com.springsource.dmserver</groupId>
    <artifactId>greenpages.parent</artifactId>
    <version>1.0.0.SNAPSHOT</version>
    <relativePath>../parent</relativePath>
  </parent>

  <modelVersion>4.0.0</modelVersion>
  <groupId>com.springsource.dmserver</groupId>
  <artifactId>greenpages</artifactId>
  <name>GreenPages PAR</name>
  <packaging>par</packaging>

  <dependencies>
  </dependencies>

  <build>
    <plugins>
    </plugins>
  </build>

</project>

This skeleton defines a basic configuration with a parent POM. Notice that the packaging type is par. When you have created this file execute the following command from the $GREENPAGES_HOME/start/greenpages directory.

mvn clean package

This command returns an error indicating that Maven does not know how to build a PAR:

[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] The plugin 'org.apache.maven.plugins:maven-par-plugin' does not exist
[INFO] or no valid version could be found
[INFO] ------------------------------------------------------------------------

The next step will correct this.
