Missing multiValued attribute in @Option

After updating to the newest args4j version I do have compile errors because of the removed “multiValued” attribute. I found the commit message which told, that it was removed because it would make no sense to have multi-value settings.

What about this case (which is simlar to mine):

@Option(name = "-in", multiValued = true, required = true)
private List<File> inFiles;

where I do support multiple ouccrences of -in (e.g. FooMain -in fileA.txt -in fileB.txt -in fileC.txt). How can this be done with the new release of args4j?

@thammegowda note that the Javadoc for StringArrayOptionHandler indicates this is expected behavior:

All of [these examples] result in a single string array that contains three tokens: banan, hruska, and jablko.

If you need proper quoting support it might be better to use the default behavior and use the flag repeatedly, i.e.:

-in "United States" -in "United Kingdom"

There are no exceptions thrown to tell that there are no operands. StringArrayOptionHandler.parseArguments will return 0

I would consider this the correct behaviour, since an empty list looks totally fine to me
