# 二、错误截图 #

## 1.错误提示： ##

Please set the JAVA_HOME variable in your environment to match the
    location of your Java installation.

## 2.原因分析 ##

打开\\maven\\apache-maven-3.3.9\\bin目录下的mvn.cmd  
你会发现maven是先去找JAVA的环境变量，如果找不到JAVA\_HOME 就会报错。所以需要将Java环境变量的名称改为JAVA\_HOME,否则MAVEN找不到JAVA 的环境变量

## 3.解决方法 ##

修改环境变量的名称JAVA\_HOME和Path
