Maven now successfully builds the PAR for your application. However, the dependecies of the PAR are not apparent. In this step the Maven dependency plugin is added to collect the transitive dependency graph for the PAR.

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

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-dependency-plugin</artifactId>
  <executions>
    <execution>
      <id>copy-dependencies</id>
      <phase>package</phase>
      <goals>
        <goal>copy-dependencies</goal>
      </goals>
      <configuration>
        <outputDirectory>${project.build.directory}/par-provided</outputDirectory>
        <overWriteIfNewer>true</overWriteIfNewer>
        <excludeGroupIds>com.springsource.dmserver</excludeGroupIds>
      </configuration>
    </execution>
  </executions>
</plugin>

Run the following command.

mvn clean package

When the command has completed, it will have copied all of the PAR’s dependencies into the target/par-provided directory. The output from Maven should include lines like these (these lines are wrapped for this document):

If the dependencies are produced, proceed to the next step.
