Maven在CentOS安装

1、下载并解压Maven

官网地址：https://maven.apache.org/docs/history.html

这里以apache-maven-3.8.6-bin.tar.gz举例，下载并上传至服务器，解压到对应目录

tar -zxvf xzvf apache-maven-3.8.6-bin.tar.gz -C /usr/local

2、建立软链接（便于版本切换）

ln -s /usr/local/apache-maven-3.8.6/ /usr/local/apache-maven

3、设置环境变量

vim /etc/profile
> M2_HOME=/usr/local/apache-maven
> PATH=$PATH:$M2_HOME/bin
> export M2_HOME PATH
source /etc/profile

4、检查安装情况

[root@localhost local]# mvn -v
Apache Maven 3.8.6 (84538c9988a25aec085021c365c560670ad80f63)
Maven home: /usr/local/apache-maven
Java version: 1.8.0_202, vendor: Oracle Corporation, runtime: /usr/local/jdk1.8.0_202/jre
Default locale: zh_CN, platform encoding: UTF-8

5、修改配置文件

备份原配置文件

cp /usr/local/apache-maven/conf/settings.xml /usr/local/apache-maven/conf/settings.xml.example

1）修改本地仓库地址

<localRepository>/usr/local/apache-maven-repo</localRepository>

2）添加阿里云镜像地址

<mirror>
  <id>alimaven</id>
  <name>aliyun maven</name>
  <mirrorOf>central</mirrorOf>
  <url>http://maven.aliyun.com/nexus/content/groups/public/</url>
</mirror>

3）关闭对http的阻止访问（注释以下配置）

<mirror>
  <id>maven-default-http-blocker</id>
  <mirrorOf>external:http:*</mirrorOf>
  <name>Pseudo repository to mirror external repositories initially using HTTP.</name>
  <url>http://0.0.0.0/</url>
  <blocked>true</blocked>
</mirror>
