How to configure multi-module Maven + Sonar + JaCoCo to get overall coverage report in Sonar?

问题

From the past one week I am trying to get code coverage of my multi module project using Sonar. My project structure is as follows.

Web Service XYX
   +- pom.xml
   +-SubFOlder
   +- Module 1
      +- pom.xml 
   +- Module 2
      +- pom.xml 
   +- Module3
      +- pom.xml 

Means I have one folder in my directory and inside that I have all my sub modules. am able to generate a jacoco.exec file in all the sub modules target directory. Want to know the way to combine all these submodules jacoco.exec so that I can get a merged code coverage in sonar report.

As I've answered here: You can put all the reports together in one folder (don't forget to call the different!) and use the merge mojo for that, or use a central unique file to all your reports by adding the flag "append":

-javaagent:append=true,destFile=/home/YourProject/report.exec

Here you'll find more information about how to configure the agent.

Hope it helps!
