> GROOVY-8577 introduced a bug: the parser incorrectly complains about missing mandatory options when the user specified --help or --version. For example:
> {code}
> java -cp ... org.codehaus.groovy.tools.GrapeMain install --version
> {code}
> ... gives the following output:
> {code}
> Missing required parameters: <group>, <module>
> Installs a particular grape
> Usage: grape install [-hv] <group> <module> [<version>] [<classifier>]
> Installs the specified groovy module or maven artifact. If a version is
