Hi, me again. Looking at the code once more, I think it's ok if you want to
make this change in the scala code and not the shell script (so, e.g., you can
unit test it), but it cannot be done in the current spot. Basically, you need
something like this:
if (args.length == 1) {
// Print deprecation warning, set log dir.
} else {
parse(args.toList)
}
That way the existing command-line parsing is not broken. With your change,
something like "--properties-file foo blah --dir /path" will successfully be
parsed, and the log directory will be set to "blah", which is not what should
happen, since that's either an invalid command line, or the directory should be
set to "/path". (I vote for invalid command line.)
