java.lang.NoSuchMethodError: com.mongodb.connection.DefaultClusterFactory.createCluster

Question

I am trying to connect MongoDB with Java. This is my code

    MongoCredential mongoCredential;
    mongoCredential = MongoCredential.createCredential(<uname>, <dbname>, <password>);
    List<ServerAddress> list = Arrays.asList(new ServerAddress("localhost", 27017));

    MongoClientSettings.Builder mongoClientSettingsBuilder = MongoClientSettings.builder()
            .credential(mongoCredential)
            .applyToClusterSettings(builder -> builder.hosts(list));

    MongoClientSettings settings = mongoClientSettingsBuilder.build();

Executing this I get the error

Exception in thread "main" java.lang.NoSuchMethodError: com.mongodb.connection.DefaultClusterFactory.createCluster(Lcom/mongodb/connection/ClusterSettings;Lcom/mongodb/connection/ServerSettings;Lcom/mongodb/connection/ConnectionPoolSettings;Lcom/mongodb/connection/StreamFactory;Lcom/mongodb/connection/StreamFactory;Ljava/util/List;Lcom/mongodb/event/CommandListener;Ljava/lang/String;Lcom/mongodb/MongoDriverInformation;Ljava/util/List;)Lcom/mongodb/connection/Cluster;

I do not know what is the reason for this. Can someone help me out with this

Did you loaded the MongoDB Java Driver? And which version did you loaded? Did you added it to your classpath? — Yonggan

Yes I have loaded the driver. I am using mongodb-driver-3.6.4 — Jackson
– Jackson, Commented Mar 25, 2020 at 13:31
I updated the driver version to 3.12.2, it worked. Thank you @Yonngan — Jackson

This may be a conflict and confusion caused by several mongodb-driver jar file that system detected. I just solve the similar problem--NoSuchMethodError with disabling mongodb-driver-sync and using spring-boot-starter-data-mongodb in pom.xml like the following one:

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
        </dependency>
<!--        <dependency>-->
<!--            <groupId>org.mongodb</groupId>-->
<!--            <artifactId>mongodb-driver-sync</artifactId>-->
<!--            <version>4.2.3</version>-->
<!--        </dependency>-->

If you have no mongodb-driver-sync which dependency provides you MongoClient?

There are multiple mongodb-driver in your sbt file. In my case, it was

libraryDependencies += "org.mongodb.scala" %% "mongo-scala-driver" % "4.5.1"
libraryDependencies += "org.mongodb.spark" %% "mongo-spark-connector" % "3.0.1"

Remove mongo-scala-driver dependency such that final build will look like this

libraryDependencies += "org.mongodb.spark" %% "mongo-spark-connector" % "3.0.1"
