Subject: Re: Closures in annotations
I’m probably overlooking something simple but I’m not seeing it yet.
The below code demonstrates the issue when trying to pass a Groovy closure to
the @Option(converter
ClosureTest.main(ClosureTest.groovy:18)
}
}

Hi all,
I have a question about passing closures to annotations in Groovy.
To illustrate, consider the @Option annotation in the picocli library.
Relevant attributes are `completionCandidates` and `converter`, defined in
Java as follows:
@Retention(RetentionPolicy.RUNTIME)
@Target
