Jacoco Report Aggregate Coverage Report issue on Sonar

Question

I have a multi-module maven project. I am facing issues while generating the sonar report for the jacoco report-aggregate coverage.

I have 2 modules (A and B) for which I want to generate the report. I have created another module (jacoco-report-aggr) under the parent module for generating the report-aggregate of jacoco.

When I run "mvn clean install", the jacoco index.html fille generated in the jacoco-report-aggr module shows the coverage for both modules A and modules B. But when I run "mvn sonar:sonar" the sonar report generated shows the coverage for only module B but not module A. Attaching the corresponding parts of the xml files.

I have the parent pom.xml as below.

<sonar.java.coveragePlugin>jacoco-maven-plugin</sonar.java.coveragePlugin>
        <sonar.dynamicAnalysis>reuseReports</sonar.dynamicAnalysis>
        <sonar.language>java</sonar.language>
        <jacoco.version>0.8.5</jacoco.version>
        <surefire.plugin.version>2.19.1</surefire.plugin.version>
        <aggregate.report.dir>jacoco-report-aggr/target/site/jacoco-aggregate/jacoco.xml</aggregate.report.dir>
        <sonar.coverage.jacoco.xmlReportPaths>/jacoco-report-aggr/target/site/jacoco/jacoco.xml,/jacoco-report-aggr/target/site/jacoco-aggregate/jacoco.xml,
            ${basedir}/../${aggregate.report.dir},
            ${basedir}/../../${aggregate.report.dir},
            ${basedir}/../../${aggregate.report.dir}</sonar.coverage.jacoco.xmlReportPaths>
