ElasticSearch SearchResponse object with aggregation to JsonObject?

Question

I am going to ask the same question again Convert SearchResponse to JsonObject

Actually I am using the same solution as mentioned in this question. But this solution is not working for me.

Below is my Elastic query:

AggregationBuilder aggregation = AggregationBuilders
                                    .terms("users")
                                     .field("USER")
                                     .size(10)
SearchResponse res = client.prepareSearch(_index)
                .setSize(0)
                .addAggregation(aggregation)
                .execute()
                .actionGet();

But when I try to convert it into a JSON object

JSONObject SRJSON = new JSONObject(res.toString());

It is saying

Constructor JSONObject(String) undefined

Remove argument to match JSONObject()

And I am using below maven plugin and elastic vs ~2.3:

<dependency>
        <groupId>com.googlecode.json-simple</groupId>
        <artifactId>json-simple</artifactId>
        <version>1.1.1</version>
</dependency>

I don't think that json-simple has JSONObject(String source) constructor and it's a compile time error. If you wish to follow the way it is being used in link to other thread, consider using the below dependency in your pom.xml:

<dependency>
  <groupId>org.json</groupId>
  <artifactId>json</artifactId>
  <version>20180813</version>
</dependency>

After including the dependency this snippet will work:

JSONObject SRJSON = new JSONObject(res.toString());

refer: JSONObject(String source)

Hope it helps!
