How to get Map key?

I have key-value pair as UUID's and trying to get key for process but it is returning value in the loop. Please help how to get key map ?

Input Value :

mapValues = [88891108-2dfd-41a1-9a92-f2200acc561c:12fd254d-98d0-4c0e-9ac9-9ccd5494075a]

code:

for(mapKey in sourceCodeMap.keySet())
{
println(sourceCodeMap[mapKey])
}

output:

12fd254d-98d0-4c0e-9ac9-9ccd5494075a

But iam expecting 88891108-2dfd-41a1-9a92-f2200acc561c as key. How to get left most value as key from map ?

The Groovy idiom is to use .each() to iterate the map:

def mapValues = ['88891108-2dfd-41a1-9a92-f2200acc561c':'12fd254d-98d0-4c0e-9ac9-9ccd5494075a']

mapValues.each { key, value ->
    println key
}
