macOS系统运行项目报错：Perhaps you are running on a JRE rather than a JDK?

在Mac上的终端输入命令 mvn clean package -e -U  进行项目的编译时，报错：

[ERROR] No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK? 

导致 “BUILD FAILURE”  

  

检查一下 Maven：

➜  ~ mvn -v

The JAVA_HOME environment variable is not defined correctly

This environment variable is needed to run this program

NB: JAVA_HOME should point to a JDK not a JRE

 

原来是编辑Java环境变量时 少了个s 啊！

   

——那么就重新编辑JAVA_HOME 环境变量，使其正确。

而后再次编译Maven项目：mvn clean package -e -U

终于 build Success ！！！！！

   

 【Reference】

1、cmd中mvn命令，出现No compiler is provided in this environment. Perhaps you are running on a JRE rather than a JDK?

 （帮助找到问题所在：发现mvn运行在jre上，应该运行在JDK上！  ）

2、Macbook idea:No compiler is provided in this environment. Perhaps you are running on a JRE...

（帮助解决：去环境变量配置文件将JAVA_HOME路径改掉！改为 JDK路径 ！）
