• 4、配置文件详解

1、下载

官网：http://maven.apache.org/download.cgi

2、解压

tar zxvf apache-maven-3.6.1-bin.tar.gz -C /opt/

解压之后的目录为 ： /opt/apache-maven-3.6.1/

3、环境变量

vim /etc/profile

在打开的文件最后面添加以下信息

export M2_HOME=/opt/apache-maven-3.6.1
export PATH=$PATH:$M2_HOME/bin

让配置生效

source /etc/profile

验证是否安装完成

mvn -version

至此，安装成功！
