Thorsten Maus (see Section A.2, “Documentation”) has developed a Maven plugin that builds a PAR file from a list of dependencies. In this step the Maven par plugin is added to properly build a PAR artifact type.

Add a <pluginRepository/> declaration to the greenpages POM file so that Maven can find the par plugin:

<pluginRepositories>
  <pluginRepository>
    <id>steademy</id>
    <name>Steademy repository</name>
    <url>http://repo.steademy.com/beta/maven2</url>
  </pluginRepository>
</pluginRepositories>

In the <build><plugins>…</plugins></build> section, add a plugin declaration for the par plugin.

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-par-plugin</artifactId>
  <version>0.2.0</version>
  <configuration>
    <fqn>true</fqn>
    <applicationSymbolicName>greenpages</applicationSymbolicName>
    <applicationVersion>${project.version}</applicationVersion>
    <applicationDescription>GreenPages PAR</applicationDescription>
    <applicationName>GreenPages PAR</applicationName>
  </configuration>
</plugin>

Declare the list of bundles to be packaged in the PAR as dependencies of the PAR project.

<dependency>
  <groupId>com.springsource.dmserver</groupId>
  <artifactId>greenpages.app</artifactId>
  <version>${project.version}</version>
</dependency>
<dependency>
  <groupId>com.springsource.dmserver</groupId>
  <artifactId>greenpages.jpa</artifactId>
  <version>${project.version}</version>
</dependency>
<dependency>
  <groupId>com.springsource.dmserver</groupId>
  <artifactId>greenpages.db</artifactId>
  <version>${project.version}</version>
</dependency>
<dependency>
  <groupId>com.springsource.dmserver</groupId>
  <artifactId>greenpages.web</artifactId>
  <version>${project.version}</version>
</dependency>

Run the following command.

mvn clean package

This command will now complete successfully and build a PAR into target/. Proceed to the next step.
