                    Important configuration options here:
                    createDependencyReducedPom: remove the shaded artifacts from the module dependencies. Without this, the
                                                original dependencies will be shaded, AND still included as transitive deps
                                                in the final POM. This is not what we want.
                    shadedArtifactAttached:     If true, the shaded artifact will be a separate JAR file for install, with
                                                the original un-shaded JAR being separate. With this being set to false,
                                                the original JAR will be modified, and no extra jar will be produced.
                    promoteTransitiveDependencies:  This will promote the transitive dependencies of the shaded dependencies
                                                to direct dependencies. Without this, we need to manually manage the transitive
                                                dependencies of the shaded artifacts.

                    Note that using <optional>true</optional> in the dependencies also allows the deps to be shaded (and
                    original dependencies to not be included), but does NOT work with promoteTransitiveDependencies
