Description

The shadowRuntimeElements is published with the publication using the Bundling.SHADOWED attribute. In Gradle's documentation for Bundling:

• external indicates that transitive dependencies are themselves component jars
• embedded indicates that transitive dependencies have been included inside the component jar, without modifying their packages
• shadowed indicates that transitive dependencies have been included inside the component jar, under different packages to prevent conflicts

With that in mind, I think it would be a good idea to check, after evaluation, if the shadowJar task is relocating dependencies. If it is, use SHADOWED. And if it isn't, use EMBEDDED. This could be especially important since Shadow's default behavior is to not relocate packages.
