How to read all file names in a directory with jenkins active choices parameter?

How can I read all file names in a directory and display them as a dropdown in Jenkins GUI?

My goal is actually creating two depending dropdowns where a user chooses a file in the first dropdown and regarding the choice, in the second dropdown, the first selected file content will be shown to the user as a parameter.

I've tried the following but without success.

In the Active Choice Parameter - Groovy Script:

import groovy.io.FileType

def list = []

def dir = new File("/some/path/to/variable/TEST/*")
dir.eachFileRecurse (FileType.FILES) { file ->
  list << file
}
return list

Here Active Choice Parameter Name is SWITCH and

In the Active Choices Reactive Parameter

import groovy.json.JsonSlurper
def list = []

File textfile= new File("/some/path/to/variable/${SWITCH}") 
JsonSlurper slurper = new JsonSlurper()
def parsedJson = slurper.parse(textfile)
parsedJson.each{ list.add(it.port_name + " " + it.description)}
return list

PS: Files are JSON formatted.

I've solved the problem so if anyone needs:

import groovy.io.FileType

def list = []

def dir = new File("/some/path/to/variable/TEST/")
dir.eachFileRecurse (FileType.FILES) { file ->
  list.add(file.getName())
}

return list

I think you miss the option Referenced parameters as in the screenshot: enter image description here

The description of this filed is here:

This option, takes a list of job parameters that trigger an auto-refresh of the Reactive Parameter when any of the 'Referenced parameters' change

Update:

For me works with your code, except one small change:

import groovy.json.JsonSlurper
def list = []

File textfile= new File("${SWITCH}")
JsonSlurper slurper = new JsonSlurper()
def parsedJson = slurper.parse(textfile)
parsedJson.each {
    list.add "$it.port_name $it.description".toString()
}
return list

I added toString() for each list element to convert the items of GString type to String. I assume this was your problem. Without toString(), Jenkins displays [Object object] because it does not know how to convert it.
