A:
Don't know if this is possible since you want to use the same map key 'age' for three different values. You'll end up overwriting the existing value with a new value.

thanks! how about using List.add() to create a new list? def rawLines = [1,2,3] def lines = [] rawLines.each { lines.add("good") } I tried above, not working..I'm just learning groovy....

A:
Does this work for you?
def newAgeList = ageList.inject([:]) { map, item -> if (!map['age']) map['age'] = []; map['age'] << item; map }
his would result in: ['age':[12, 13, 23]]
Otherwise, you can get the literal value as something like:
def newAgeList = ageList.collect { "age:$it" }
his would result in: ['age:12', 'age:13', 'age:23']
A third option:
def newAgeList = ageList.collect { ['age':it] }
This would result in: [['age':12], ['age':13], ['age':23]]
Unfortunately, you can't do this as a map like you showed above as map keys must be unique.
Really it all depends on what you are trying to do with the result.
