Maven dependency directory not created in target

Question

I'm using Maven 3.3.3 to create a Spring MVC application that can be deployed to Heroku. I intend to use jetty-runner as suggested by the Heroku documentation (https://devcenter.heroku.com/articles/getting-started-with-spring-mvc-hibernate).

I can't get Maven to create the target/dependency folder in which to copy the jetty-runner.jar file. I use the commands:

mvn clean
mvn package

I get the target directory created, with all resources, web pages and source, but not the "target/dependency" folder where the jetty-runner.jar file should be copied.

My pom.xml is almost identical to the one provided by the sample application in the link above. My project and pom.xml file can be found in the following GitHub repository:

Add an activation of your dependency-plugin outside the <pluginManagement> section:

...
<build>
  <pluginManagement>
    <plugins>
      <!-- Leave as is -->
      ...
    </plugins>
  </pluginManagement> 
  <!-- Add the section below -->  
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-dependency-plugin</artifactId>
    </plugin>
  </plugins>
</build>      
...

The <pluginManagement> section is for declaring how your plugins should behave when activated. The activation itself is done outside this section.
