This example contains an -outfile option that is not allowed in the packager command syntax.
javafxpackager -createbss -srcdir src\css -srcfiles stylesheet.css -outdir styles -outfile stylesheet
The -outfile option is not included in the list of options for the -createbss task command and should be deleted.
If you run the command with the -outfile parameter, it runs without an error but the option is ignored. The outfile name is always the same as the srcfile name with a .bss extension.
