> The `DefaultMapStructFinder` is unable to locate the `Mapper` classes when
> running in Spring Boot. Seems to throw an exception calling
> `PluginHelper.getPackageScanClassResolver(ecc).findByFilter(f ->
> f.getName().endsWith("Mapper"), names);` inside the `doInit()` method.
> You can work around this by creating your own `MapStructFinder`, extending
> `DefaultMapStructFinder`, overriding the `doInit()` function, and calling
> `discoverMappings(...)` with each of your `Mapper` classes. That way it
> doesn't try to scan the classpath to find the `Mapper` classes automatically.
> I've attached a working example to illustrate.
> *Note: It has no issue locating them when running `mvn spring-boot:run`. Only
> when running from the packaged uber jar with `java -jar ...`.
