spring-boot-maven-plugin not pulling in dependent classes into jar - spring

Question

Im having a problem with the spring-boot-maven-plugin whereby it is not including the dependent classes in the resulting jar file.
In the docs, it states that dependencies with scope provided will be included in the jar file, but I cant get it to include them.
I have a project with 2 sub-modules: model and restServer. In the model module, I want to use swagger to codegen based on an openApi input model. The resulting classes are put in a jar file: model/target/rest-model-0.0.1-SNAPSHOT.jar.
In the restServer module, I have the Spring RestController and Application java code, and want to "pull in" the model classes into the resulting jar file: restServer/target/rest-server-0.0.1-SNAPSHOT.jar with the spring-boot-maven-plugin builder, but its not including anything from the model sub-module.
The entire project structure and pom files are listed below.
How can I get the spring-boot-maven-plugin to pull in the class files from the model sub-module, effectively creating a "fat" self-contained jar?

Answer 1

The dependencies are placed in BOOT-INF\lib\ of the repackaged JAR file.
This path will be added to the classpath of you Spring Boot Application.
