I have downloaded the three JAR files to connect to my MongoDB database. I have placed them in a folder of name twitter4j, due to the project I'm currently working on.

I make the imports in my code as follows:

import com.mongodb.async.client.MongoClient;
import com.mongodb.async.client.MongoDatabase;

And I have also tried in this way:

import com.mongodb.MongoClient;
import com.mongodb.client.MongoDatabase;

following your documentation. But when I try to compile the code, it throws me the following error:

error: package com.mongodb.async.client does not exist for the first case and

error: cannot find symbol
import com.mongodb.MongoClient; for the second one.

I have reviewed the content of JAR files and that classes does not exist in any case.
