Hi,

You've got a lot going on in that Maven command. First, since you're using Maven, you don't need to specify things like where the source files are; the scanner will pick that up automatically. Second, when you run the first part of that command:

                    mvn install \
                     org.jacoco:jacoco-maven-plugin:0.8.0::prepare-agent

where is your test report generated to? I'm guessing it's not "src".
