studio git无法提交并提示Another git process seems to be running in this......

Git操作的过程中显示

Another git process semms to be running in this repository, e.g. an editor 
opened by ‘git commit’. Please make sure all processes are terminated then 
try again. If it still fails, a git process remove the file manually to continue… 

也就是git被另外一个程序占用，重启机器也不能够解决。原因在于Git在使用过程中遭遇了奔溃，部分被上锁资源没有被释放导致的。

解决方案：

进入项目文件夹下的 .git文件中（需要显示隐藏文件夹）删除index.lock文件即可。
