ClassNotFoundException: com.mongodb.connection.DefaultClusterFactory #23

I'm using this dependency with spring-boot 2.7.9:

<dependency>
            <groupId>de.flapdoodle.embed</groupId>
            <artifactId>de.flapdoodle.embed.mongo.spring27x</artifactId>
            <version>4.6.2</version>
</dependency>

And:

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
</dependency>

But the error below persists on running Junit 4 tests. What might be missing?

@gcdelgado i guess that this is some kind of dependency version stuff.. maybe some dependency is missing or more than one version of the same dependency is present.. (for the later i use the maven enforcer plugin).. your IDE should show you your current class path and this way you can check if the class should be present.

@gcdelgado still an issue? reopen if needed..
