Looping in a C-style For loop instead of using each - jenkins

Question

how can i loop through a json file using a FOR loop in groovy? I am able to do it with .each but i am in a situation/bug where i cannot use .each loops.
The json file is being read and parsed into an object.
The json looks like this:
{
"workflows1": {
"name": "/wf_multifolder",
"file": "release1/wf_multifolder.XML",
"folderNames": {
"multifolder": "{{multifolder}}",
"agent1": "{{agentx}}"
}
},
"workflows2": {
"name": "/wf_multifolder",
"file": "release1/wf_multifolder.XML",
"folderNames": {
"multifolder": "{{multifolder}}",
"agent1": "{{agentx}}"
}
}
}
Note: i can modify the json file, if need to make the process simpler.. All i am try to do is to loop throgh and extract the values for the keys.

So given the json in a String like so:
def jsonText = '''{
"workflows1": {
"name": "/wf_multifolder",
"file": "release1/wf_multifolder.XML",
"folderNames": {
"multifolder": "{{multifolder}}",
"agent1": "{{agentx}}"
}
},
"workflows2": {
"name": "/wf_multifolder",
"file": "release1/wf_multifolder.XML",
"folderNames": {
"multifolder": "{{multifolder}}",
"agent1": "{{agentx}}"
}
}
}'''
You can just do:
import groovy.json.*
def json = new JsonSlurper().parseText(jsonText)
for(entry in json) {
println "$entry.key has file $entry.value.file"
}
to print:
workflows1 has file release1/wf_multifolder.XML
workflows2 has file release1/wf_multifolder.XML
