maven-surefire-report-plugin 2.8 error: org.apache.maven.doxia.siterenderer.sink.SiteRendererSink.unknown

Question

My project started to fail during the execution of mvn site:site since I updated the maven-surefire-report-plugin to version 2.8, which was just released a week or so ago.

Here is the exception:

Here is the relevant section of my pom file:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-surefire-report-plugin</artifactId>
  <version>2.8/version>
  <configuration>
    <argLine>-Xmx512m</argLine>
  </configuration>
</plugin>

Switching back to version 2.7.2 results in no error. Anyone knows more about this? Thanks.

From http://jira.codehaus.org/browse/SUREFIRE-714

As can be seen from http://maven.apache.org/plugins/maven-surefire-report-plugin/

"Note: As of version 2.8 this plugin requires Maven Site Plugin 2.1 or higher to work properly. Version 2.7.2 and older are still compatible with newer surefire versions, so mixing is possible."

For all practical purposes you can stay on 2.7.2 as long as you want, since the xml format used for interchange will stay backward compatible (newer surefire versions can use older surefire-report-plugins). You will, of course, be missing out on bugfixes in reporting if you choose to not upgrade reporting-plugin/site.

If you don't have the maven-site-plugin mentioned in your pom it won't pull in the latest version. Add it as specified in http://maven.apache.org/plugins/maven-site-plugin/plugin-info.html
