Maven packs the transitive dependencies also into the archive files. We can exclude specific transitive dependencies by using <exclusions>
To list transitive dependencies that are packed into the archive file, there is maven-dependency-plugin.

Include the following under plugins and invoke any of the maven life cycle phase like mvn install dependency:tree

<plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-dependency-plugin</artifactId>
</plugin>
