All my .go files are reported to be "excluded for coverage"

Changing the paths to “./fileutils” does not seem to have changed the behaviour or the issuing of exluded debug messages:

08:15:43.116 DEBUG: 'tools/api/feature/wire_gen.go' indexed with language 'go'
08:15:43.116 DEBUG: File tools/api/feature/wire_gen.go excluded for coverage

I shall comment out the sonar.coverage.exclusions= property and then I will try changing the paths to “fileutils” instead.
