[原]failed to create a child event loop

系统、软件版本：windows7 64bit，intellij IDEA14.1.4 ；

在使用Intellij IDEA的时候出现的问题，一次重启后，编译工程就会出现如题的错误：

Error:Abnormal build process termination:

网上的一些资料显示是因为安装了avira等防病毒软件或者是windows防火墙没关，这两个都试了下，还是不行，intellij idea也是卸载重装，同样不行。

同时，还出现的问题是ping 机器名不同，但是ping ip是通的，比如，ping www.baidu.com提示机器名写错等等，ping ip就是通的；因为之前ping 机器名是通的，就想到会不会是之前卸载什么软件的时候把网络弄乱了。按照这个思路，就修复网络，下载了个360，然后修复下网络。网络修复后，ping www.baidu.com是通的，然后再次打开idea ，发现ok了。

分享，成长，快乐

脚踏实地，专注
