明确子父模块结构

父目录是带modules
大致结构如下：

   <modules><module>ruoyi-admin</module><module>ruoyi-framework</module><module>ruoyi-system</module><module>ruoyi-quartz</module><module>ruoyi-generator</module><module>ruoyi-common</module><module>ruoyi-ems</module></modules><packaging>pom</packaging>

像打包出现这样的报错就是子模块打包方式使用了pom

Failure to find com.ruoyi:ruoyi-framework:jar:3.8.5 in https://maven.aliyun.com/repository/public was cached in the local repository, resolution will not be reattempted until the update interval of public has elapsed or updates are forced

应该使用jar的打包方式。

jar，war，pom的区别

JAR、WAR 和 POM 是 Java 开发中常见的三种文件类型，它们在项目构建和部署过程中起着不同的作用。

JAR（Java Archive）：JAR 文件是一种用于存储 Java 类、资源文件和库的归档文件格式。它通常用于打包和发布 Java 应用程序、库或模块。JAR 文件可以包含多个类文件和相关的资源文件，并且可以通过 Java 虚拟机（JVM）来运行。JAR 文件可以被其他 Java 项目依赖引用，使得代码复用和模块化开发更加方便。
WAR（Web Application Archive）：WAR 文件是一种用于打包和部署 Web 应用程序的归档文件格式。WAR 文件中包含了 Web 应用程序的 Java 类、资源文件、静态资源（如 HTML、CSS、JavaScript 文件）以及部署描述符（如 web.xml）。WAR 文件可以被部署到支持 Java Servlet 规范的 Web 容器（如 Tomcat、Jetty）中，并通过容器提供的 HTTP 服务来访问 Web 应用程序。
POM（Project Object Model）：POM 是 Maven 构建工具使用的 XML 文件，用于定义和管理项目的各种元数据和配置信息。POM 文件描述了项目的依赖关系、构建生命周期、插件配置、仓库信息等。它是 Maven 构建过程中的核心文件，通过读取和解析 POM 文件，Maven 可以自动化地执行编译、测试、打包、部署等操作。

总结：

JAR 是用于打包 Java 类和相关资源的归档文件格式，用于代码的发布和复用。
WAR 是用于打包和部署 Web 应用程序的归档文件格式，包含了 Web 相关的类、资源和描述符，用于 Web 应用的部署和访问。
POM 是 Maven 项目的配置文件，用于定义项目的元数据和构建配置，通过读取和解析 POM 文件，Maven 可以自动化地完成各种构建任务。

配置pom打包方式的意思是使用maven分模块管理，都会有一个父级项目，pom文件一个重要的属性就是packaging（打包类型），一般来说所有的父级项目的packaging都为pom，packaging默认类型jar类型，如果不做配置，maven会将该项目打成jar包。

子模块都是jar包
在这里插入图片描述
父模块是ruoyi，其它都是子模块。
有时需要按照顺序clean 和 install。我这里都配置好了，只要在父工程中install就行。然后就会获得一个target文件夹，里面有我们要的打包好的程序jar包

admin模块细节部分：
会有build部分

<build><plugins><plugin><groupId>org.springframework.boot</groupId><artifactId>spring-boot-maven-plugin</artifactId><version>2.1.1.RELEASE</version><configuration><fork>true</fork> <!-- 如果没有该配置，devtools不会生效 -->

贴出所有的pom.xml文件吧
common的
