Bson cannot be resolved with Mongo DB /Java

Question

I am getting this error on the last line in code below: The type org.bson.conversions.Bson cannot be resolved. It is indirectly referenced from required .class files, I am using Mongo JavaDriver 3.0.2

 import com.mongodb.BasicDBObject;
 import com.mongodb.DB;
 import com.mongodb.DBCollection;
 import com.mongodb.Mongo;
 import com.mongodb.MongoClient;
 import com.mongodb.util.JSON;

public class InsertDriver {

public static void main(String[] args) 
{

    Mongo mongo = new Mongo("localhost", 27017);
    DB db = mongo.getDB("postsdb");
    DBCollection collection = db.getCollection("posts");

    BasicDBObject doc1 = new BasicDBObject();
    doc1.put("user", "Mike");
    doc1.put("sports", "soccer");
    doc1.put("tweet", "Hi..");

    //String json = JSON.serialize( doc1);
    //BasicDBObject bson = (BasicDBObject) JSON.parse( json );

    List<BasicDBObject> docs = new ArrayList<BasicDBObject>();
    docs.add(doc1);

    collection.insert(docs);  //ERROR HERE

 }

}

Had the same issue. I've solved it by downloading the bson jar and adding it to the search path.

The Mongodb documentation states the following:

You can also download the jars directly from sonatype. Note: mongodb-driver requires the following dependencies: bson and mongodb-driver-core
