Attempts

The following jq statement returns all downloadUrls:

You can use method Pluck/1

package main

@Kvaz1r you are correct! @030 you can use pluck,

package main

import (
	"fmt"

	"github.com/thedevsaddam/gojsonq"
)

const data = `{
  "items" : [ {
    "downloadUrl" : "http://localhost:8081/repository/maven-releases/file2/file2/1.0.0/file2-1.0.0.jar",
    "path" : "file2/file2/1.0.0/file2-1.0.0.jar",
    "id" : "bWF2ZW4tcmVsZWFzZXM6ZDQ4MTE3NTQxZGNiODllYzQzMTI5MDdhYzdiOWUyMDM",
    "repository" : "maven-releases",
    "format" : "maven2",
    "checksum" : {
      "sha1" : "d9f877a857a7e9928eac04d09a59f25967624155",
      "sha256" : "0a8cac771ca188eacc57e2c96c31f5611925c5ecedccb16b8c236d6c0d325112",

`

func main() {

	res := jq.From("items").Pluck("downloadUrl")
	fmt.Printf("Pluck: %v\n", res)
