Usage

To make the default code coverage tool:

1. Log in as an administrator
2. Go to Settings > Configuration > General Settings > Java
3. Set the 'sonar.java.coveragePlugin' property to 'emma'

To activate Emma on some projects:

1. Add the 'sonar.java.coveragePlugin=emma' when executing the maven plugin. This can be set in pom.xml or in command line.

2. Or use the 'reuseReports' mode:

   Code Block
   title reuseReports mode language html/xml
   <sonar.dynamicAnalysis>reuseReports</sonar.dynamicAnalysis> <!-- Path to the directory with .ec and .em Emma files --> <sonar.emma.reportPath>emmaDir</sonar.emma.reportPath>

Known Limitations

Branch coverage is not calculated as such notion does not exist in Emma.
