git错误解决 -- 小结

1.今天 当我 执行 Git add somefile 的时候，出现 如下 错误：

If no other git process is currently running, this probably means a
git process crashed in this repository earlier. Make sure no other git
process is running and remove the file manually to continue.

解决方法：

[code]rm -f ./.git/index.lock

[/code]

2. 编译ICS时 出现 如下错误：

build/core/Java.mk:20: *** dalvik/dexgen: Invalid LOCAL_SDK_VERSION '4' Choices are: current . Stop.

解决方法：

rm -rf prebuilt ; repo sync prebuilt
