You could do somehting like this:

import wslite.rest.RESTClient

class App {

    static void main(String[] args) {
        RESTClient client = new RESTClient("http://localhost:8080/")
        def path = "/demo"
        def response = client.get(path: path)
        List listOfNumbers = response.json
        println listOfNumbers
    }
}

That RESTClient is provided by groovy-wslite. In Gradle you could express that dependency with something like this:

implementation 'com.github.groovy-wslite:groovy-wslite:1.1.3'

Alternatively you could use a standalone script like this:

@Grab("com.github.groovy-wslite:groovy-wslite:1.1.3")
import wslite.rest.RESTClient

RESTClient client = new RESTClient("http://localhost:8080/")
def path = "/demo"
def response = client.get(path: path)
List listOfNumbers = response.json
println listOfNumbers
