maven涉及的配置

1、settings.xml

（1）本地仓库

<localRepository>d:\temp\repo</localRepository>，用 <localRepository>括起来的表示本地仓库的位置。

（2）镜像源

<mirrors>

<mirror>

<id>nexus-aliyun</id>

<mirrorOf>central</mirrorOf>

<name>Nexus-aliyun</name>

<url>https://maven.aliyun.com/nexus/content/groups/public\</url>

</mirror>

</mirrors>

阿里镜像

2、pom.xml相关依赖

<dependencies>
    <dependency>
        <groupId>org.apache.hadoop</groupId>
        <artifactId>hadoop-common</artifactId>
        <version>3.1.3</version>
