2. Copy the java file into your repository.
3. Set the full class name of the selected strategy as a value of org.springframework.modulith.core.ApplicationModuleDetectionStrategy property in resources/META-INF/spring.facrories.

Motivation

We started using Spring Modulith to enforce better structured application code. As the default settings worked nicley we soon faced an regarding to modules that should live inside sub-packages.

Context

Our application consumes services and store their responses. Later on it operates on the saved data. Separating of service client and internal data handling seemd a good idea, but resulted package structure that caused conflict in module detection.
