okhttp3 java.lang.NoClassDefFoundError: kotlin/jvm/internal/Intrinsics

I m following this tutorial : https://scrapingant.com/blog/web-scraping-java to scrap with java.

I created a java project and when I try to execute this code from the tutorial :

import java.io.IOException;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

public class App {
    public static void main(String[] args) throws IOException {
        final App scraper = new App();
        final String htmlContent = scraper.getContent();
        final String extractedTitle = scraper.extractTitle(htmlContent);
        System.out.println(extractedTitle);
    }

    private String getContent() throws IOException {
        final OkHttpClient client = new OkHttpClient.Builder().build();
        final String urlToScrape = "https://example.com";
        final Request request = new Request.Builder().url(urlToScrape).build();
        final Response response = client.newCall(request).execute();
        return response.body().string();
    }

    private String extractTitle(String content) {
        final Pattern titleRegExp = Pattern.compile("<title>(.*?)</title>", Pattern.DOTALL);
        final Matcher matcher = titleRegExp.matcher(content);
        matcher.find();
        return matcher.group(1);
    }
}

but i get this error :

I can't find why and fix this error.

To import okhttp i had to download a jar file from maven central (4.9.3) and then in vscode : java project -> add the jar file to the Referenced Libraries.

I am a beginner in Java and want to clarify that I am not particularly attached to okhttp. If another simpler/efficient library exists, I'm not against it. I just want to be able to scrape in java and then integrate the code into an android application !

Thanks in advance
