解决在旧版本上repo init时候fatal: bad object XXX的错误
环境：Mac OS X 10.8
问题：在ics版本的Android源码库上运行repo init来升级到jb，出现下列错误
repo init -u git://gitorious.org/rowboat/manifest.git -m rowboat-jb-am37x.xml

解决方案：
cd /Volumes/Project/rowboat-jb/.repo/manifests
git fetch 同步下manifests
git diff 查看未提交的修改
git stash 保存修改
cd ../..
repo init -u git://gitorious.org/rowboat/manifest.git -m rowboat-jb-am37x.xml
repo sync
