Sonarqube, getting Zero Code Coverage for scala project - scala

Question

I am scanning the scala multi-module project. I am getting the module reports as:
[INFO] Statement coverage.: 36.07%
[INFO] Branch coverage....: 6.25%
[INFO] Coverage reports completed.
[DEBUG] Mojo execution time: 2516 ms
But still getting
[DEBUG] 08:48:16.724 Sensors : Zero Coverage Sensor
[INFO] 08:48:16.725 Sensor Zero Coverage Sensor
[INFO] 08:48:16.756 Sensor Zero Coverage Sensor (done) | time=31ms
The coverage report on sonar dashboard is 0%
The jacoco.exec and jacoco.xml reports are also getting generated.
Below is section from pom:

What am I missing? I am struggling to get the code coverage on sonar dashboard. Please help..

Not sure if this is the same case, but we had a similar issue using Scoverage and the problem was related to the path where the reports were generated, it seems that SonarCloud was looking at a different path. We solved it by replacing paths like this:
sed -i -e 's/\/home\/github\/_work\/my-scala-project\/my-scala-project\/src/\/github\/workspace\/src/g' target/scala-2.13/scoverage-report/scoverage.xml
In our case the paths correspond to a GitHub Action.
