#Maven构建项目 #Maven本地仓库配置 #Maven中央仓库配置

本文介绍了如何配置Maven的本地仓库，并详细说明了如何从Maven模板创建一个新的项目。通过修改settings.xml文件，设置本地仓库路径为D:/apache-maven-3.6.0/re，以及使用阿里云仓库作为镜像以提高下载稳定性。此外，还演示了在C:Userswangx目录下创建名为Student的Maven项目。

配置Maven本地仓库

  1. 在D:/apache-maven-3.6.0目录下新建re文件夹，该目录用作maven的本地库。

  2. 打开maven安装目录下的 \conf\settings.xml文件，查找下面这行代码：

<localRepository>/path/to/local/repo</localRepository>

localRepository节点默认是被注释掉的，需要把它移到注释之外，然后将localRepository节点的值改为本地仓库目录
例如

<localRepository>D:/apache-maven-3.6.0/re</localRepository>
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<!--<mirrorOf>central</mirrorOf> -->
<mirrorOf>*</mirrorOf>
</mirror>
  1. localRepository节点用于配置本地仓库，本地仓库其实起到了一个缓存的作用，它的默认地址是 C:\Users\用户名.m2。

当我们从maven中获取jar包的时候，maven首先会在本地仓库中查找，如果本地仓库有则返回；如果没有则从远程仓库中获取包，并在本地库中保存。

  1. maven默认从中央数据仓库中下载数据，由于maven默认中央数据仓国内链接有时访问不稳定，建议做如下设置：
    打开maven安装目录下的 \conf\settings.xml文件，查找找到mirror节点，修改为阿里云数据仓库。
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<!--<mirrorOf>central</mirrorOf> -->
<mirrorOf>*</mirrorOf>
</mirror>

从 Maven 模板创建一个项目
