The forked VM terminated without saying properly goodbye. VM crash or System.exit called

1/問題描述

項目框架 spring+springMVC+mybatis
用maven管理項目
IDE：STS

執行maven install時報錯

2/問題分析

有人說是
TestCase寫了不正常的 System.exit() 語句

或System.exit() 沒有正常關閉
*具體問題我沒有發現

3/我是把測試類刪除，再maven install 正常，再把測試類重新添加，再一次maven install還是正常（攤手）。

不知道問題出在哪里，但是目前異常已經解決
