新安装的 IDEA 未配置 JDK+Maven 所以打开若依框架无运行按钮

步骤 1：配置本地 JDK（必须最先做）

1.1 打开 JDK 设置

顶部菜单栏File → Project Structure...（快捷键Ctrl+Alt+Shift+S）

1.2 配置 Project SDK

1. 左侧选中Project
2. Project SDK 下拉框 →Add SDK → Download JDK...
   • 若本地已有 JDK8/11：选Add SDK → JDK，选中你本地 JDK 根目录
   • 推荐下载：Amazon Corretto 8（若依专用 JDK8）
3. Project language level 选择8 - Lambdas, type annotations etc.
4. 点击Apply

1.3 配置模块语言级别

左侧切换Modules

1. 选中根项目、ruoyi-admin、ruoyi-common 等所有模块
2. Language level 统一改为8
3. Apply 保存

步骤 2：配置 Maven（安装 + IDEA 绑定）

2.1 如果你还没装 Maven，先安装（前面教程步骤简化版）

1. 下载apache-maven-3.8.6，解压到纯英文无空格路径E:\software\apache-maven-3.8.6
2. 配置系统环境变量MAVEN_HOME+ Path 添加%MAVEN_HOME%\bin
3. 修改conf/settings.xml：
   • 配置本地仓库路径
   • 粘贴阿里云镜像加速下载
4. cmd 输入mvn -v验证安装成功

2.2 IDEA 内绑定 Maven

1. 顶部File → Settings → Build, Execution, Deployment → Build Tools → Maven
2. Maven home path：选择你解压的 maven 文件夹E:\software\apache-maven-3.8.6
3. 勾选OverrideUser settings file，选中 maven 目录下conf/settings.xml
4. Local repository 会自动读取你配置的本地仓库
5. Apply → OK

2.3 加载项目 Maven 依赖

1. IDEA 右侧边栏找到Maven面板（没看到就View → Tool Windows → Maven）
2. 点击左上角刷新图标（Reload All Maven Projects）
3. 等待右下角进度条走完，自动下载所有 jar 依赖，代码红色报错消失
