The `@silent` annotation, when it's only added with `Provided` as in ``` "com.github.ghik" % "silencer-lib" % silencerVersion % Provided cross CrossVersion.full ``` causes ``` java.lang.NoClassDefFoundError: com/github/ghik/silencer/silent ... Caused by: java.lang.ClassNotFoundException: com.github.ghik.silencer.silent ... ``` The workaround is to add `silencer-lib` as a hard _non-Provided_ dependency. But that is of course problematic in its own right.
