No unit test success reported to sonar

Question

A gradle build is creating a jacoco report which is picked up by sonar runner. After the sonar results are pushed to the sonar server, unit test coverage is displayed but unit test success is 0 even though all tests are run successfully.

Looking at the sonar runner log I see the following items reporting the source and classes locations:

15:52:36.087 INFO  - Source dirs: /poc-sonar/src/main/java
15:52:36.087 INFO  - Test dirs: /poc-sonar/src/test/java, /Volumes/Disk/Development/poc-sonar/src/test/groovy
15:52:36.088 INFO  - Binary dirs: /poc-sonar/build/classes/main

This is raising the first question: Does Sonar have to see the compiled test classes for analysis?

Further down the log:

15:52:37.435 INFO  - Sensor JaCoCoSensor...
15:52:37.445 INFO  - Analysing /poc-sonar/build/jacoco/test.exec
15:52:37.546 INFO  - No information about coverage per test.
15:52:37.548 INFO  - Sensor JaCoCoSensor done: 113 ms
15:52:38.105 INFO  - Execute decorators...
15:52:38.580 INFO  - Store results in database

Jacoco has picked up the test.exec file, but reporting "No information about coverage per test"

What does that log statement mean? The sonar server actually exposes correct coverage! Is it an indicator for the missing test success reported by Sonar? What is missing for getting the unit

Unit Tests Coverage
50,0%
50,0% line coverage

Unit test success

In recent Sonar versions, the Sonar property for test report location has been renamed from sonar.surefire.reportsPath to sonar.junit.reportsPath. Hence you may have to set the latter manually. For example:

apply plugin: "sonar"

subprojects {
    apply plugin: "java"
    sonarRunner {
        sonarProperties {
            property "sonar.junit.reportsPath", test.reports.junitXml.destination
        }
    }
}
