Answer 1

You can create a gradle task like this

gradle myTask{
 doLast{
  def inputFile = new File("xyz.json")
  def json = new JsonSlurper().parseText(inputFile.text)
  def labels = json.properties.foo.type //This will return "pqr"
 }
}

Answer 2

If you want to parse a json file in build.gradle.kts do as follows:

import groovy.json.JsonSlurper
val VersionsMap: Map<String, String> by extra {
    JsonSlurper().parse(file("xyz.json")) as Map<String, String>
}
val value = VersionMap.get("key")

Gradle build scripts are just Groovy scripts. Read the Gradle User Guide to learn how to write custom tasks, and use the JsonSlurper class to parse your json file.
