I wondered that there is no commit for this an then realized that I have
to do that on my own in the pom.xml for each project, because Maven will
download its plugins:

<build> 
  <pluginManagement>
    <plugin>
      <artifactId>maven-surefire-plugin</artifactId>
      <version>2.20</version>
    </plugin>
     ...
</build>

Thanks for fixing so quickly. Yes, closing with this message.
