部署多功能模块依赖项目中解决的问题

介绍
问题一：如何让打包出来的Gateway.jar对UserManagement.jar的依赖
问题二：在阿里云流水线上打包报错找不到父模块的pom

介绍

做一个用户管理项目，采用的Spring-Cloud技术，还没确定最终的项目结构，所以展示的只是整个项目的一部分（Eureka在另一个工程中），我要说的工程是完整的，工程整体结构如下图所示。

在部署该工程过程中主要遇到两个问题，两个问题均与pom.xml文件有关系，在此主要讨论pom文件的设置。展示pom文件如下，Gateway模块依赖UserManagement模块且两个模块均需要生成jar包提供给系统执行。

以上是解决问题后的pom文件

问题一：如何让打包出来的Gateway.jar对UserManagement.jar的依赖

从网上找了些资料，有说换mvn命令的，有说将build标签放在父pom中的，有说可以只在依赖包中设置build标签打出包含所有它依赖包的jar文件。实践证明，mvn命令的效果是一样的（尽管过程中有时甚至都过不了mvn打包环节的，而且一会过了一会儿过不了）；如果最终你想让子模块打出的包通过java -jar命令运行出来（运行不出来报什么清单的错），就必须在子pom文件中声明build标签。最终我在maven多模块项目中子模块可以运行，打包报错找到答案：需要将UserManagement模块的普通包和可执行包分开生成，既能执行也能提供Gateway的依赖。

问题二：在阿里云流水线上打包报错找不到父模块的pom

参考链接：maven报错Non-resolvable parent POM---pom找不到parent指明relativePath的值即可（由于我指明的值是relativePath的默认值，所以我认为可能的原因是需要展开relativePath标签，至少本地测试没问题）
