NoSuchMethodError: void com.mongodb.MongoClient.<init> when migrating to newer driver version

Question

I am migrating a jar from using the 3.0 version of mongo driver to 5.1. I am using java SE 11. In my local environment, the tests work ok, but when in the web environment, I get the following error:

java.lang.NoSuchMethodError: 'void com.mongodb.MongoClient.< init >(java.util.List, java.util.List, com.mongodb.MongoClientOptions)' at deployment.VUCE.war//com.genexusconsulting.mongodb.GXCMongoDBConector.createClient(GXCMongoDBConector.java:811) at deployment.VUCE.war//com.genexusconsulting.mongodb.GXCMongoDBConector.connect(GXCMongoDBConector.java:106)

The line that is referring to has the following code:

    List<ServerAddress> seeds = new ArrayList<ServerAddress>();
    seeds.add(new ServerAddress(host, port));
    CodecRegistry codecRegistry = CodecRegistries.fromRegistries(CodecRegistries.fromProviders(new QueryResponseCodecProvider()), MongoClientSettings.getDefaultCodecRegistry());
    ConnectionString cnn = new ConnectionString(mongoUri);
    /* here there be error */
    MongoClientSettings options = MongoClientSettings.builder().
                    applyConnectionString(cnn).
                    applyToClusterSettings(builder -> builder.hosts(seeds)).
                    codecRegistry(codecRegistry).build();
    /* here there be error */

The pom file includes:

<!-- https://mvnrepository.com/artifact/org.mongodb/bson -->
<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>bson</artifactId>
    <version>5.1.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.mongodb/mongodb-driver-core -->
<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongodb-driver-core</artifactId>
    <version>5.1.2</version>
</dependency>
<!-- https://mvnrepository.com/artifact/org.mongodb/mongodb-driver-sync -->
<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongodb-driver-sync</artifactId>
    <version>5.1.2</version>
</dependency>

For which, the files that I include on my lib folder are: bson-5.1.2.jar, bson-record-codec-5.1.2, mongodb-driver-core-5.1.2.jar and mongodb-driver-sync-5.1.2.jar, while also removing all previous versions. The code works fine in my local tests, but it fails when I include it in a test environment.

I will do my best to help you, because I see that you haven't received any help yet. Hope to be of help.

The first thing I would say is to check if you have to make changes to your code (Connect to MongoDB) as you have updated the driver version. Here you have another link to see if you are using any deprecated class/method. For example, I see the following in the exception you have passed com.mongodb.MongoClient which is now com.mongodb.client.MongoClient. So it looks your code is still compatible with 3.X version instead of the 5.X version.

If after this you are still having problems, here you have a link to another answer, in case it helps you.

Note: With the command mvn dependency:tree (link) you can see the dependency tree for your project and ensure if any library is bringing in any older version.
