Help building example portlet for 1.1.0-beta2

Hi,

I'm trying to install the example portlet that I downloaded from:
http://wiki.apache.org/portals/Pluto/Pluto1%2e1ExamplePortlet

The instructions tell you to run:

mvn integration-test

When I run that command I get the following error:

[ERROR] BUILD ERROR

Reason: Unable to download the artifact from any repository

  org.apache.maven.plugins:maven-pluto-plugin:pom:1.1.0-beta2

from the specified remote repositories:
  central (http://repo1.maven.org/maven2)
