Found It!!
From this thread
, here is the key to getting the Cobertura plugin to work:
<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <systemProperties> <property> <name>net.sourceforge.cobertura.datafile</name> <value>target/cobertura/cobertura.ser</value> </property> </systemProperties> </configuration> </plugin>
Enjoy!
