明確子父模塊結構

父目錄是帶modules
大致結構如下：

   <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>

像打包出現這樣的報錯就是子模塊打包方式使用了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

應該使用jar的打包方式。

jar，war，pom的區別

JAR、WAR 和 POM 是 Java 開發中常見的三種文件類型，它們在項目構建和部署過程中起著不同的作用。

JAR（Java Archive）：JAR 文件是一種用于存儲 Java 類、資源文件和庫的歸檔文件格式。它通常用于打包和發布 Java 應用程序、庫或模塊。JAR 文件可以包含多個類文件和相關的資源文件，并且可以通過 Java 虛擬機（JVM）來運行。JAR 文件可以被其他 Java 項目依賴引用，使得代碼復用和模塊化開發更加方便。
WAR（Web Application Archive）：WAR 文件是一種用于打包和部署 Web 應用程序的歸檔文件格式。WAR 文件中包含了 Web 應用程序的 Java 類、資源文件、靜態資源（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 規范的 Web 容器（如 Tomcat、Jetty）中，并通過容器提供的 HTTP 服務來訪問 Web 應用程序。
POM（Project Object Model）：POM 是 Maven 構建工具使用的 XML 文件，用于定義和管理項目的各種元數據和配置信息。POM 文件描述了項目的依賴關系、構建生命周期、插件配置、倉庫信息等。它是 Maven 構建過程中的核心文件，通過讀取和解析 POM 文件，Maven 可以自動化地執行編譯、測試、打包、部署等操作。

總結：

JAR 是用于打包 Java 類和相關資源的歸檔文件格式，用于代碼的發布和復用。
WAR 是用于打包和部署 Web 應用程序的歸檔文件格式，包含了 Web 相關的類、資源和描述符，用于 Web 應用的部署和訪問。
POM 是 Maven 項目的配置文件，用于定義項目的元數據和構建配置，通過讀取和解析 POM 文件，Maven 可以自動化地完成各種構建任務。

配置pom打包方式的意思是使用maven分模塊管理，都會有一個父級項目，pom文件一個重要的屬性就是packaging（打包類型），一般來說所有的父級項目的packaging都為pom，packaging默認類型jar類型，如果不做配置，maven會將該項目打成jar包。

子模塊都是jar包
在這里插入圖片描述
父模塊是ruoyi，其它都是子模塊。
有時需要按照順序clean 和 install。我這里都配置好了，只要在父工程中install就行。然后就會獲得一個target文件夾，里面有我們要的打包好的程序jar包

admin模塊細節部分：
會有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> <!-- 如果沒有該配置，devtools不會生效 -->
<!--                    <mainClass>com.ruoyi.RuoYiApplication</mainClass>--></configuration><executions><execution><goals><goal>repackage</goal></goals></execution></executions></plugin><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-war-plugin</artifactId><version>3.1.0</version><configuration><failOnMissingWebXml>false</failOnMissingWebXml><warName>${project.artifactId}</warName></configuration></plugin></plugins><finalName>${project.artifactId}</finalName></build>

貼出所有的pom.xml文件吧
common的
