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