-------------------------------------------------------------
This is a breaking change if you were expecting the picocli dependency to be
in the Groovy distribution. It is listed as a runtime dependency if you use
{{groovy-cli-picocli}} but just not by default in the distribution. You can of
course add a {{@Grab}} to scripts or place the jar in your distro or
{{~/.groovy}} folder. I'll add a note in the release notes.

> Grape cannot pull in picocli

> Key: GROOVY-9165
> URL: https://issues.apache.org/jira/browse/GROOVY-9165
> Project: Groovy
> Issue Type: Improvement
> Components: Grape, groovy-runtime
> Affects Versions: 2.5.0, 2.5.1, 2.5.2, 2.5.3, 2.5.4, 2.5.5, 2.5.6, 2.5.7
> Reporter: Remko Popma
> Assignee: Paul King
> Priority: Major
> Labels: breaking
> Fix For: 3.0.0-beta-2
>
> Time Spent: 20m
> Remaining Estimate: 0h
>
> If I try to run a Groovy script I am unable to pull in a newer version of
> picocli via {{@Grab}}:
> {code:groovy}
> @Grab('info.picocli:picocli-groovy:4.0.0-beta-1b')
> @GrabExclude('org.codehaus.groovy:groovy-all')
> @picocli.groovy.PicocliScript
> @picocli.CommandLine.Command
> import picocli.CommandLine
> println "Groovy version ${GroovySystem.version}"
> println "Picocli version $CommandLine.VERSION"
> {code}
> Depending on the Groovy version, this prints
> {code}
> Groovy version 2.5.0
> Picocli version 3.0.2
> {code}
> or
> {code}
> Groovy version 2.5.7
> Picocli version 3.9.5
> {code}
> So the {{@Grab('info.picocli:picocli-groovy:4.0.0-beta-1b')}} is not honoured.
> This is because the {{groovy.ui.GroovyMain}} class, which executes Groovy
> scripts, itself uses picocli to parse the command line parameters.
> Unfortunately, this means that Groovy script authors cannot control the
> picocli version used by their scripts.
> Is there anything we can do to improve this?
