brew install maven@3.5
# 注意安装过程中出现以下输出
...
If you need to have maven@3.5 first in your PATH run:
  echo 'export PATH="/usr/local/opt/maven@3.5/bin:$PATH"' >> ~/.zshrc

（2）配置环境变量

vim ~/.bash_profile

# 加入内容
export PATH=/usr/local/opt/maven@3.5/bin:$PATH

# 使配置文件生效
source ~/.bash_profile

# 验证
mvn -v
