Just in case someone has run into this recently, the code coverage
report doesn't graph results properly and shows everything as 100%.
This is even the case with some public sites like the PMD plugin.
(Notice how everything is 100%, I'm skeptical that's real:
http://maven.apache.org/plugins/maven-pmd-plugin/cobertura/index.html)
http://jira.codehaus.org/browse/MCOBERTURA-61
i.e.
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.0</version>
</plugin>
