Apache Maven版本升级-Windows
Windows电脑升级Apache Maven版本的步骤如下：
一、下载最新版本的Maven安装包:
安装包可从官网下载：https://maven.apache.org/download.cgi
如果下载速度太慢，可使用此安装包 apache-maven-3.8.4-bin.zip
二、确保本机jdk环境变量已配置完，maven-3.8.4 要求至少JDK 7 才能运行；
Microsoft Windows [版本 10.0.19042.1165]

C:\Users\Administrator>java -version
openjdk version "1.8.0_41"
OpenJDK Runtime Environment (build 1.8.0_41-b04)
OpenJDK Client VM (build 25.40-b25, mixed mode)
C:\Users\Administrator>
本机JDK环境是1.8满足条件；
三、开始安装
1.解压下载的安装包到安装目录（目录必须全英文）
命令操作方式(举例)：unzip apache-maven-3.8.4-bin.zip
2.解压完是一个目录 apache-maven-3.x.y ，如下：
3.将apache-maven-3.x.y下的bin文件路径添加到环境变量PATH中，如下：
命令操作(举例)：set PATH=“D:\develop\xyd\apache-maven-3.8.4\bin”;%PATH%
C:\Users\Administrator>mvn -version
