Since SonarQube 6.2, the concept of coverage type (unit/IT/overall) was dropped. Instead a Sensor can save multiple coverage reports (with no specific type) per file.
The behavior should be
|reportPath & itReportPath||honor||honor & print deprecation notice|
|reportPaths||ignore; no coverage||honor|
Note that "honor" behavior is specified for SQ versions 6.1 and lower to not break backward compatibility with the LTS version.
