        The dependency analysis has found a dependency that is either:

        1) Used and undeclared: These are available as a transitive dependency but should be explicitly
        added to the POM to ensure the dependency version. The XML to add the dependencies to the POM is
        shown above.

        2) Unused and declared: These are not needed and removing them from the POM will speed up the build
        and reduce the artifact size. The dependencies to remove are shown above.
