Hi Olivier,
Thanks for the quick response! A little sleep and your reply prompted me to double check what was being included in the scan. I realized there was a libraries folder which must have had some Java files in it. So, instead of pointing it to a dummy dir for the java binaries, I was able to just exclude the libraries directory (which is all third-party stuff anyways) using -Dsonar.exclusions=path/to/libraries/folder. Thanks for your help!!
