今天在下載andriod原始碼，特來與大家分享一下我的經驗。

當然，網上教下載原始碼的教程較多，本文主要針對在GFW下下載原始碼出現的各種問題的解決方法。

1、首先安裝下載clientgit , curl。

命令例如以下：

sudo apt-get install curl git

2、建立一個bin資料夾，加入到PATH當中。

mkdir ~/bin
PATH=~/bin:$PATH

3、下載repo的指令碼並加入可執行許可權。

curl http://git-repo.googlecode.com/files/repo-1.13 > ~/bin/repo
chmod a+x ~/bin/repo
 

在這裡。問題就出來了。

自5月底開始，谷歌的相關網站，基本上都已經不能直接訪問了，當然，我一直用goagentFQ，所受影響不大。除了打不開tools.android.com這個網站之外。

在這裡。我假設你已經有代理工具的了（假設沒有，會折騰的用goagent，不會折騰的一個月花幾塊錢買一個）。

以下我們就須要設定curl的代理，方法非常easy。加個引數 -x 代理地址。

比方我的代理server為我在局域網裡的還有一部電腦。IP為192.168.137.1，埠為8087.那麼上面下載 repo指令碼的命令就應該為：

curl -x 192.168.137.1:8087 http://git-repo.googlecode.com/files/repo-1.13 > ~/bin/repo
 

下載之後，再改動許可權，如上面所看到的。

4、建立原始碼資料夾並進入。

mkdir android4.4.2
cd android4.4.2

5、初始化repo。

repo init -u https://android.googlesource.com/platform/manifest -b android-cts-4.2_r2

在-b後面跟著的是分支名。不出意外，這裡問題又來了。googlesource.com網站被牆。所以這裡不能直接下載，須要設定程式碼。這裡設定程式碼非常easy，設定一下https.proxy的變數就能夠了。

例如以下：

https_proxy=192.168.137.1:8087

後面相應的值記得改回你自己的代理server地址及埠。

（補述，http的代理也要設定 。後面下載程式碼會用到，方法同上。設定一下http_proxy變數。

）

然後我們再執行初始化。這時。問題又來了。控制檯輸出：

Get https://code.google.com/p/git-repo/
error: server certificate verification failed. CAfile: /etc/ssl/certs/ca-certificates.crt CRLfile: none while accessing https://code.google.com/p/git-repo/info/refs
fatal: HTTP request failed

顯示是證書問題。匯入證書我不知道怎麼整，只是我找到了還有一種方法，就是取消GIT的SSL驗證。命令例如以下：

export GIT_SSL_NO_VERIFY=1

然後我們再執行初始化，這時成功了（假設網路斷開請多試一試）。

6、下載原始碼。

最後，執行repo sync就可以。

7、關於獲取原始碼清單

以下說一下怎樣獲取各個版本號的分支名。

首先。沒有設定代理的要先設定GIT的代理，例如以下：

export https_proxy=192.168.137.1:8087
export https_proxy=192.168.137.1:8087
export GIT_SSL_NO_VERIFY=1

當中第一、二行各自是設定http及https的代理server。後面的值改動為你自己的取代server的地址。

第三行是取消SSL驗證，不然會出現SSL驗證問題。

然後執行以下命令克隆該git 倉庫。

 git clone https://android.googlesource.com/platform/manifest

接著執行git branch -a，就可以得到各分支名，例如以下：

[email protected]:~/code/A/manifest$ git branch -a

最後。附上我已經下載好的原始碼：http://zdz.la/KN8Nai。

我下載的東西，事實上有51G左右，當中.repo佔了約42G。下載原始碼請留夠硬碟
