下载：https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

解压之后，复制目录：/Users/onns/Downloads/java/apache-maven-3.6.3

因为系统更新后，命令行从bash换成了zsh所以环境变量文件也改了：.zshrc

echo 'export M2_HOME=/Users/onns/Downloads/java/apache-maven-3.6.3/bin' >> .zshrc
echo 'export MAVEN_HOME=/Users/onns/Downloads/java/apache-maven-3.6.3' >> .zshrc
echo 'export PATH=$MAVEN_HOME/bin:$PATH' >> .zshrc

让环境变量生效：

1
source .zshrc
