My settings:
Still see 0.0% for excluded path… should show -- and not counting them.
Hello @keithcml,
Can you attach the logs of the scan (preferably ran in DEBUG by setting sonar.verbose=true) for me to investigate why it does not work?
FYI if your screenshot is a part of sonar-project.properties file and not a piece of cmd line I am guessing that the problem is simply that you added the double quotes and you should not. The exclusions may be seen a single value (not several comma separated values) that no path would match

Oh… I can get the right calculation by removing the quote… thanks … you save my day
Glad to help ! 
Enjoy SonarQube
