If you are building an uberjar or "shaded jar", make sure your meta inf service files are merged. (This bit me multiple times on a dropwizard project.)

If you are using the gradle shadowJar plugin, you want to call mergeServiceFiles() in your shadowJar target: https://github.com/johnrengelman/shadow#merging-service-files

Not sure what the analogous commands are for maven or other build systems.
