Hi,

I need to write a command line script in groovy and here's the first attempt (test of course ;]):

When I invoke the script with 'groovy bs.groovy' the following message is displayed:

error: Missing required option: v
usage: usage TODO
-h,--help usage information
-v,--version <version> global version settings
No options entered!
usage: usage TODO
-h,--help usage information
-v,--version <version> global version settings


Is it possible to catch the situation where no options are entered? In such case I'd just like to display the usage info.

Also when the script is invoked with 'groovy bs.groovy -h' the same error messages is displayed. How to prevent parsing when 'help' option is present? In such case I'd like to display the usage info (ignoring the rest of options) and exit.

Any help would be greatly appreciated.
