Multi module Scala project gives 0% sonar code coverage - scala

Question

I am using SonarQube Enterprise EditionVersion 7.9.1. I am running maven goal for my multi-module scala project as :
mvn clean org.jacoco:jacoco-maven-plugin:prepare-agent verify org.sonarsource.scanner.maven:sonar-maven-plugin:3.4.0.905:sonar
After successfull completion, I am getting 0% code coverage. Below is my sonar.properties:
sonar.junit.reportsPath=target/surefire-reports
sonar.surefire.reportsPath=target/surefire-reports
sonar.jacoco.reportPath=target/coverage-reports/jacoco-unit.exec
sonar.binaries=target/classes
sonar.java.coveragePlugin=jacoco
sonar.verbose=true
Below is pom.xml

I am getting the coverage as 0%, when there are many unit test written. How should I fix this?
