Target/jacoco.exec aggregated and target/site/jacoco/jacoco.xml are created but they are not posted into sonarqube

SonarQube Server / Community Build

SonarQube, 6.7.5.38563
Code Analyzer for Java * 5.7 (build 15470) installed

I have a multimodule maven project. I have defined a separate coverage module ( as suggested on jacoco document).
I am trying to import the jacoco coverage files into sonarqube to get unit test coverage showing in sonar.

myproject
   pom.xml
      module1
         pom.xml
      module2
         pom.xml
      coverage
         pom.xml

after running:

mvn clean install

I get the following directory created on the same level as the parent pom.xml

target/jacoco.exec

2755133 Oct 6 17:28 jacoco.exec

target/site/jacoco/jacoco.xml

6982975 Oct 6 17:34 jacoco.xml

Then I execute:

mvn -P sonar4 sonar:sonar

When I check the logs I cannot see that

Here is a snippet:

[INFO] -------------  Scan mje

I can see that analysis is done for each module when I run sonar.

[INFO] Sensor JaCoCoSensor [java]
[INFO] Analysing /repo/eraonel/git/myproject/engine/…/target/jacoco.exec
[INFO] No information about coverage per test.
[INFO] Sensor JaCoCoSensor [java] (done) | time=252ms

So my questions are now:

  1. Why is not sonar executing Sensor JaCoCoSensor [java] on the files that are in, myproject/target?
  2. Why is sonar not posting the results ( have both jacoco.exec and jacoco.xml) to sonarqube.

Ps . With all the information that you can google I wonder if anyone got this working!

No ideas :thinking: Where can I find the code for the jacoco sensor?
