  3. Is the report updated at each build and contains valid files information? Especially file paths.
  4. Are you using the sonar.coverage.jacoco.xmlReportPaths parameter?
  5. Do you pass the report by its right path?
  6. Turn on the analysis debug mode and check what says the Sensor JaCoCo XML Report Importer [jacoco] sensor, it will likely help.
