The forked VM terminated without saying properly goodbye

大家好，又见面了，我是你们的朋友全栈君。

 一直在使用Maven开发项目，最近遇到了一个让人头疼的问题，在网上搜索竟然没有找到中文描述的解决方式，自己找了英文网站才明白原因并解决问题，故自己撰写此文，以便同行查阅。

     在maven项目中使用maven install命令时，出现The forked VM terminated without saying properly goodbye异常，具体问题如下：

    自己查找了半天，才知道原来在写单元测试的时候，测试结束时写了一行 System.exit(0); 造成了vm提前退出，去掉之后再次执行maven install正常。

    解决方式，在idea中使用Ctrl+Shift+R 查找项目中的System.exit(0)代码行，然后删除之，我的项目删除之后执行mvn install正常。
