Cannot resolve symbol error for JSONArray in IntelliJ with Java

Question

I have added the following in my POM file within IntelliJ (I'm using Maven)

     <dependency>
        <groupId>com.googlecode.json-simple</groupId>
        <artifactId>json-simple</artifactId>
        <version>1.1</version>
     </dependency>

But for my code I am getting Cannot Resolve Symbol error when creating a "JSONArray" object.

I have tried using import org.json.jsonarray and import org.json.simple.jsonarray

I have exited IntelliJ and rebuilt the project. I don't see what I am doing wrong.

 public class Countries {

   private static String url;
   private static int count;
   private static int sCode;
   private static List<CountriesData> cList;

  public void GetCountries() throws Exception
   {
      try        {
         url = "http://restcountries.eu/rest/v1/all";

         // make get request to fetch json response from restcountries
         Response resp = get(url);

         //Fetching response in JSON as a string then convert to JSON Array
         JSONArray jsonResponse = new JSONArray(resp.asString());

Running "File | Invalidate Caches" helped in this case.
