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.
As a result, the Java plugin should be updated. When the runtime is SonarQube 6.2+:
- log a warning when property sonar.jacoco.itReportPath is used
- deprecate sonar.jacoco.reportPath and introduce sonar.jacoco.reportPaths to accept a comma separated list of coverage reports
