Download the latest code for this plugin.

Modified the pom to include an scm section (as 
org.apache.maven.plugins:maven-plugins) doesn't point to the sandbox (where 
this plugin is currently located)
{noformat}
  <scm>
    
<connection>scm:svn:http://svn.apache.org/repos/asf/maven/sandbox/plugins/</connection>
    
<developerConnection>scm:svn:https://svn.apache.org/repos/asf/maven/sandbox/plugins/</developerConnection>
    <url>http://svn.apache.org/viewcvs.cgi/maven/sandbox/plugins/</url>
  </scm>
{noformat}

Added in the reporting section as suggested bu Dennis
{noformat}
<reporting>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-changelog-plugin</artifactId>

        <reportSets>
          <reportSet>
            <id>triple-report</id>

              <report>file-activity</report>
            </reports>
          </reportSet>
        </reportSets>
      </plugin>
    </plugins>
  </reporting>
{noformat}

and commented out Jason's id (since his is one that appears in the reports and 
is also in the developer section:
{noformat}
<!--
      <id>jvanzyl</id>
 -->
{noformat}

After installing the plugin and then running mvn site, I now get no npe's.

> NPE when developer section does not include an id
