Hi @sergek,  
Could you try to check your maven configuration and command line using this guide: [[Coverage & Test Data] Importing JaCoCo coverage report in XML format](https://community.sonarsource.com/t/coverage-test-data-importing-jacoco-coverage-report-in-xml-format/12151)?  
Then could you check the content of `target/site/jacoco-aggregate/jacoco.xml` to figure out if the xml file does not contain coverage information or if `JaCoCo XML report importer` is not able to import the coverage report.
