Question

我在spring-boot-maven-plugin上遇到了问题，即它不在生成的jar文件中包括依赖类。

在docs中，它声明jar文件中将包含范围为provided的依赖项，但我无法使其包含它们。

我有一个包含2个子模块的项目：model和restServer。在model模块，我想使用招摇CODEGEN基于一个OpenAPI的输入模型。结果类放在一个jar文件中：model/target/rest-model-0.0.1-SNAPSHOT.jar。

在restServer模块中，我具有Spring RestController和Application Java代码，并且想要将model类“拉入”到生成的jar文件中：restServer/target/rest-server-0.0.1-SNAPSHOT.jar与{ {1}}构建器，但不包含spring-boot-maven-plugin子模块中的任何内容。

下面列出了整个项目结构和pom文件。

如何获取model从spring-boot-maven-plugin子模块中提取类文件，从而有效地创建一个“胖”的自包含jar？

Answer 1

依赖关系放在重新打包的JAR文件的BOOT-INF \ lib \中。

此路径将被添加到您的Spring Boot Application的类路径中。

spring-boot-maven-plugin没有将依赖类拉入jar
