How to create a simple JSON in Groovy using JsonBuilder?

tool_name = 'test
product_name = 'test'
platform_name = 'test'

def my_json = new JsonBuilder()
def root = my_json name: tool_name, product: product_name, platform: platform_name
print my_json

What am I doing wrong? I am trying to create a very basic (flat) json object to later send in a POST request.

something like: 

{'name': 'test', 'product': 'test', 'platform': 'test'}

What is the easiest way to do this? Can I use JsonBuilder or Slurper for this? I am completely new to groovy.

You can simply use a Map and render it as JSON using groovy.json.JsonOutput.toJson() helper method, e.g.

def tool_name = 'test'
def product_name = 'test'
def platform_name = 'test'

def map = [name: tool_name , product: product_name , platform: platform_name]

def json = groovy.json.JsonOutput.toJson(map)

println​ json​

This example produces following output:

{'name': 'test', 'product': 'test', 'platform': 'test'}

If you want to use groovy.json.JsonBuilder then below example produces your expected output:

def tool_name = 'test' 
def product_name = 'test' 
def platform_name = 'test'

def builder = new groovy.json.JsonBuilder()        
builder {
    name tool_name
    product product_name
    platform platform_name
}
println builder.toString()​

groovy.json.JsonSlurper class is dedicated to reading JSON documents and manipulating them if needed.
