Maven 配置依赖包安装路径

独立于 Eclipse 安装 Maven 工具时

修改 Maven 全局配置文件以更改依赖包安装地址

全局配置文件为 <Maven_安装目录>/conf/setting.xml（安装目录为 bin 目录所在的目录）。

<!-- <maven_install_direcotry>/conf/setting.xml-->
<?xml version="1.0" encoding="UTF-8"?>

<!-- ... -->

<settings xmlns="http://maven.apache.org/SETTINGS/1.2.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd">
  <!-- localRepository
   | The path to the local repository maven will use to store artifacts.
   |
   | Default: ${user.home}/.m2/repository
  -->
  <!-- 修改此行即更改依赖包安装路径（此行初始状态时处于上文注释中） -->
  <localRepository>E:\SOFT\programming\package-manage\maven\apache-maven-3.9.6\repository</localRepository>

<!-- ... -->

</settings>

命令行查看配置文件信息

使用 mvn help:effective-settings 命令打印 Maven 有效设置信息。这个命令会考虑所有的配置文件（全局 settings.xml 文件、用户 settings.xml 文件、项目 pom.xml 文件）。

PS maven> mvn help:effective-settings

使用 Eclipse 内置 Maven 工具时

从 菜单栏 > Window > Preferences 打开偏好设置窗口。从窗口侧边栏中找到 Maven > User Settings。修改其中的 Global Settings 或是 User Settings 为自定义的 settings.xml 文件（配置内容可参考 <Maven_安装目录>/conf/setting.xml 文件）。点击 Update Settings 后即会自动更新 Local Repository（不可手动修改）。点击 Apply 后即应用。
