Groovy - Convert object to JSON string

Question

I m pretty used to Grails converters  where you can convert any object to a JSON representation just like this  http   grails org Converters Reference   return foo as JSON   But in plain groovy  I cannot find an easy way to do this  http   groovy-lang org json html   JSONObject fromObject this    return empty json strings     Am I missing an obvious Groovy converter    Or should I go for jackson or gson library

Do you mean like   import groovy json    class Me       String name    def o   new Me  name   tim     println new JsonBuilder  o   toPrettyString
