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?

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.
