Ok, shading can be tricky. Do you have this file inside the shaded jar: >> "META-INF/services/org.apache.cayenne.configuration.server.CayenneServerModuleProvider"
And if you do, can you check the contents of it? It is a simple text file, so once you extract it form the jar, you can check it in any text editor.
