执行gradle的时候，grable报错，报错内容有个关键的信息 JAVA_HOME must be set to build Elasticsearch
但是我的本机电脑已经配置了JAVA_HOME，很迷惑！！！
不过我们可以通过报错内容定位到对应的代码位置：
代码位置：org/elasticsearch/gradle/BuildPlugin.groovy
再执行一下，果然返回了null值，我晕了，我的机器明明是配置了的
先不纠结本地JAVA_HOME了，直接上骚操作，把 compilerJavaHome 获取逻辑改下，不从JAVA_HOME中获取，直接配置成路径：
String compilerJavaHome = "/Users/你的用户名/Library/Java/JavaVirtualMachines/temurin-11.0.14.1/Contents/Home"
先改成这个逻辑，就可以运行了～
