download source workspace

 新建一个source存放目录     

mkdir WORKING_DIRECTORY
cd WORKING_DIRECTORY

repo init

---

$ repo init -u URL [OPTIONS] 

Installs Repo in the current directory. This creates a .repo/ directory that contains Git repositories for the Repo source code and the standard Android manifest files. The .repo/ directory also contains manifest.xml, which is a symlink to the selected manifest in the .repo/manifests/ directory.

Options:

• -u: specify a URL from which to retrieve a manifest repository. The common manifest can be found at 

• -m: select a manifest file within the repository. If no manifest name is selected, the default is default.xml.

• -b: specify a revision, i.e., a particular manifest-branch. (see info from URL)

$ repo init -u   -b android-4.4_r1

repo sync
 开始同步代码             


*下面有一个防止下载时掉线的sh脚本，感觉不错，转自网上                 

#! /bin/bash
echo "=====start repo sync======"  
repo sync  
while [ $? = 1 ]; do  
echo “======sync failed, re-sync again======”  
sleep 3  
repo sync  
done
