As you know, SonarQube does not do the analysis , just imports the results.

You really ought to upgrade to SQ LTS 8.9.x, which means going to 6.7.7 , then 7.9.6 , then to 8.9.x .

Your coverage issues is that you must jacoco:prepare-agent , then run tests ( -DskipTests=false ), then produce ajacoco:report , or since you are multi-module, jacoco:report-aggregate and finally, sonar:sonar

The sonar-jacoco plugin can then pick the results up from the sonar.coverage.jacoco.xmlReportPaths location(s).

If "'sonar.coverage.jacoco.xmlReportPaths" is not defined, default locations are:

"target/site/jacoco/jacoco.xml,target/site/jacoco-it/jacoco.xml,build/reports/jacoco/test/jacocoTestReport.xml"

SonarJava analyzer V 5.12. deprecated use JaCoCo's binary format ( .exec files) . Support for .exec format JaCoCo Coverage Reports was dropped in SonarQube 8.2

According to the release notes for the sonar-jacoco-plugin-1.1 , it now has " Support wildcard in sonar.coverage.jacoco.xmlReportPaths "

SonarQube explains why the numbers might not match expectations
