To be more specific, I added:
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-surefire-plugin</artifactId>
<version>2.2</version>
<configuration>
<forkMode>always</forkMode>
</configuration>
</plugin>
</plugins>
</build>
to the pom.xml in the killlerapp-store-xstream project.
