1、去官网下载你需要的maven包

https://maven.apache.org/download.cgi
image-1709273455760

image-1709273482970

image-1709273502667

2、创建目录并解压文件

cd /home
mkdir -p local/maven
cd /home/local/maven
chmod 777 maven
tar zxvf apache-maven-3.5.4-bin.tar.gz

3、配置maven环境

vim /etc/profile
#文件添加以下内容
# maven environment
export M2_HOME=/home/local/maven/apache-maven-3.5.4
export CLASSPATH=$CLASSPATH:$M2_HOME/lib
export PATH=$PATH:$M2_HOME/bin
 
#输入命令使配置文件生效
source /etc/profile

测试是否安装成功

mvn -v

4、修改maven下载地址

mkdir repository
#修改文件夹权限
chmod 777 repository/

#进入maven的conf目录

cd /home/local/maven/apache-maven-3.5.4/conf
chmod 777 settings.xml

<localRepository>/home/local/maven/repository</localRepository>
... ...
<mirror>
    <id>nexus-aliyun</id>
    <mirrorOf>central</mirrorOf>
    <name>Nexus aliyun</name>
    <url>http://maven.aliyun.com/nexus/content/groups/public</url>
