The plugin normally generates 3 reports: changelog, dev-activity and file-activity. By default all three reports are generated. It is possible to configure the plugin so that only a few of these reports are generated. This is done using <reportSets>.
The following configuration will generate only the changelog and file-activity reports.
Note: The reportSets element is not part of the configuration element. Instead, the configuration is found inside the reportSet element.
