spring-boot-maven插件没有将依赖类拉入jar



Im在spring-boot-maven-plugin中遇到问题,因为它没有将依赖类包括在生成的jar文件中。

在文档中,它声明具有作用域provided的依赖项将包含在jar文件中,但我无法让它包含它们。

我有一个包含两个子模块的项目:modelrestServer。在model模块中,我想使用swagger来基于openApi输入模型的代码生成。生成的类被放在一个jar文件中:model/target/rest-model-0.0.1-SNAPSHOT.jar

restServer模块中,我有Spring RestController和Application java代码,并希望将model类"拉入"到生成的jar文件中:使用spring-boot-maven-plugin构建器的restServer/target/rest-server-0.0.1-SNAPSHOT.jar,但它不包括来自model子模块的任何内容。

下面列出了整个项目结构和pom文件。

如何让spring-boot-maven-pluginmodel子模块中提取类文件,从而有效地创建一个"胖"的自包含jar?
