java.lang.NoClassDefFoundError: com/mongodb/connection/BufferProvider

Question

I'm trying to connect to mongoDB server from Java Servlet.
I added the following jars: bson-3.0.4.jar, mongodb-driver-3.0.4-javadoc.jar, mongodb-driver-core-3.0.4.jar and add this jars also to WEB-INF\lib directory.

And when i tried to run the following code:

MongoClient mongoClient = new MongoClient("localhost",27017);

I got the following exception:

java.lang.NoClassDefFoundError: com/mongodb/connection/BufferProvider

What i'm doing wrong?

Did you check out here, i think you need additional jar file.

Couldn't it be better to use a dependency management like Maven or Gradle? I prefer to delegate someone else to resolve my dependencies...
