错误如下：

> Exception in thread "main" java.lang.IllegalArgumentException: Can not find tools.jar under java home: /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home, please try to start arthas-boot with full path java. Such as /opt/jdk/bin/java -jar arthas-boot.jar

## 问题 ##

macOS Big Sur系统，使用Gralde在Terminal编译时，提示`Could not find tool.jar. Please check that /library/internet plug-ins/javaappletplugin.plugin/contents/home contains a valid jdk installation.`

## 原因 ##

未配置`JAVA_HOME`，编译时找到了JRE的目录，而JRE目录则不包含tool.jar。

## 方法 ##

1、使用`/usr/libexec/java_home -V `查看JDK目录

> **/usr/libexec/java\_home -V** 
> 
> Matching Java Virtual Machines (2): 
> 
>           1.8.211.12 (x86\_64) "Oracle Corporation" - "Java" /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home 
> 
>           1.8.0\_211 (x86\_64) "Oracle Corporation" - "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0\_211.jdk/Contents/Home /Library/Java/JavaVirtualMachines/jdk1.8.0\_211.jdk/Contents/Homes

2、设置JAVA\_HOME

> vi ~/.bash\_profile
> 
> export JAVA\_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0\_211.jdk/Contents/Home

3、使其生效

>  source ~/.bash\_profile
