When I ran the code from Listing 14.17, I received the error:

Caught: groovy.lang.MissingMethodException: No signature of method: groovy.json.JsonSlurper.parse() is applicable for argument types: ( values: [data/plan.json]
Possible solutions: parse(, use([Ljava.lang.Objectsmilie, wait(), grep(), any(), wait(long)

The issue was corrected by modifying the applicable line of code to:

def plan = new JsonSlurper().parse(new File('data/plan.json').newReader())

Re: Listing 14.17 Issue
Alternatively, you can use the 2.2.0-beta-1 version of Groovy which has the required method. Thanks.
