分了多个模块，exam-web 里面有 @SpringBootApplication 类作为启动类，exam-web 里面和 exam-file 模块里面都有 Controller
在 idea 里面运行的时候，可以正常访问 exam-file 模块的 controller 接口，但 mvn install 打包以后，java -jar 启动 exam-web target 下的 jar 包，访问不到 exam-file 模块的接口, 解压 jar 包看了下是没有打包进去，exam-web 的 dependencies 里面已经添加了 exam-file 模块
想请教下，如何才能全部打包到一个 jar 里面
项目结构如下
├─.idea ├─.mvn │ └─wrapper ├─config ├─exam-common │ ├─src ├─exam-file │ └─src │ └─main │ └─java ├─exam-web │ └─src │ ├─main │ │ ├─java │ │ └─resources │ └─test └─logs ├─debug ├─error └─info 各个 pom.xml 文件内容（太长，省略了一些第三方依赖包）：

 | 1 zsdroid 2023 年 10 月 13 日  1 没有扫描到呗。启动类里加上 exam-file 的包名。 |
| 2 zsdroid 2023 年 10 月 13 日 1 另外<module>exam-file</module>放在<module>exam-web</module>前面 |
 | 3 retanoj 2023 年 10 月 13 日 1 在 idea 里运行的时候，观察一下运行的 java 命令。你会发现 java -classpath 里跟了一堆.jar 包 |

 | 6 chocotan 2023 年 10 月 13 日 1 spring-boot 的 maven plugin 从 parent 里面删掉 |
 | 7 diagnostics 2023 年 10 月 14 日 1 spring-boot-maven-plugin 是普通 Spring 应用打包所有依赖到同一个包的插件。 你在 Root 的 POM 里面定义了 build 里面用了它，意味着所有子模块都会继承这个插件。 正确做法是：在 Root 里移除 spring-boot-maven-plugin ，放到 Web 项目里面就好，其他的模块你不用来发布出去给其他人用的话，只定义一个 maven-compiler-plugin ，能够编译出来就可以了。。。 |
