Hello,
First of all I want to tell you that you are running an old sonarqube version which is not supported since a long time. I strongly recommend you to upgrade to a more recent version being 7.9.x or 8.0.
Coming to your question, you can find all you need in the documentation.
We also have a JaCoCo dedicated thread on this community forum.
As you will read in this latest thread, the JaCoCo format we are using now is the XML format, not the binary format any more. The support of XML format come with a much more recent version of the analyser than the one you are probably running.
So in my opinion, your first move would be to upgrade SonarQube and the scanners you are using and then focusing on importing code coverage.
Regards,
Alex.
