Remko Popma updated GROOVY-8578:
--------------------------------
Description:
The picocli version of CliBuilder has an {{errorWriter}} property
({{System.err}} by default) that is used to print the error message and usage
help to when the user provided invalid input on the command line. This prevents
error messages from inadvertently being parsed by another program when the
output of a groovy program is piped to another program.
The previously existing {{writer}} property is used when the user requests help
with {{--help}} or {{--version}}. This allows users to pipe the output of the
help request to {{less}} or {{grep}} or another utility.
I think this improvement also makes sense for the commons-cli version of
CliBuilder. I can raise a PR if there is interest.
