unable to resolve class JsonGenerator

Hi,

I have this very simple groovy script:

----------------------------------------------------------

import groovy.json.JsonBuilder;
import groovy.json.JsonGenerator;

def id = " ";

def generator = new JsonGenerator.Options()
.excludeNulls()
.build()

JsonBuilder builder = new JsonBuilder(generator)
builder {

name id?.trim() ? id : null
make 'Holden'
year 2006
country 'Australia'
}

println builder.toString();

----------------------------------------------------------

There is nothing wrong in the code but I get this error when I ran it in CPI:

javax.script.ScriptException: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed: buildJsonForUpdatedFields__Script.gsh: 4: unable to resolve class groovy.json.JsonGenerator

Is there a way to upgrade the groovy version? Or is there a way to explicitly use the latest groovy version, if yes how??

    This is resolved.

    The only thing I need to do is to upload the "groovy-json-2.5.7.jar" file on the resource tab as archive and that's it. No need to change any code for import.

    You can download the file here:
