repo sync faild, xxx does not appear to be a git repository

repo init -u git://xxx.xxx.xxx.xxx/aosp-mirror/platform/manifest.git -b android-4.4_r1

repo sync:
Initializing project platform/abi/cpp ...
fatal: '../platform/abi/cpp.git' does not appear to be a git repository
fatal: The remote end hung up unexpectedly
error: Cannot fetch platform/abi/cpp

modify ".repo/manifest.xml" fetch from ".." to "git://10.19.133.153/aosp-mirror"

i don't know why fetch path is ".." after repo init, but if you meet the same problem you can try to modify fetch path in yours android source path
