The maven team is pleased to announce the Maven Clover Plugin 1.7-SNAPSHOT 
release! 

http://maven.apache.org/reference/plugins/clover/

The Clover plugin allows measuring test coverage using Clover 
(http://www.cenqua.com/clover). 

Changes in this version include:

  New Features:

o Added maven.clover.includes and maven.clover.excludes properties to specify 
  what files to include/exclude from the Cloverification. Issue: MPCLOVER-25. 
  Thanks to Michael Gaffney. 

  Fixed bugs:

o Do not create a Clover report link when the project has no tests. Issue: 
  MPCLOVER-21. 
o clover:off should now reset correctly the maven.build.dest property that 
  clover:on modifies. Note that the reported error has been fixed even though 
  I have not been able to reproduce the problem (and hence we don't have a 
  test for it). Issue: MPCLOVER-28. 

  Changes:

o Open Clover report page in a new window in the same manner as it's done for 
  the Javadoc and XRef reports. Issue: MPCLOVER-22. Thanks to Maarten Coene. 
o Added new maven.clover.execute.during.report property to control whether or 
  not the clover-report goal builds Cloverify the sources and execute the 
  tests (defaults to true). Issue: MPCLOVER-18. 
o Deprecated maven.clover.database.dir property and replaced it with a 
  maven.cover.database property that contains not only the database directory 
  but also the name of the database file. Issue: MPCLOVER-24. 
o Upgraded Clover to version 1.3.4. Issue: MPCLOVER-26.
