下載Android源代碼時,出現這個錯誤php
Traceback (most recent call last): File "E:\LocalProject\Oreo\.repo\repo/main.py", line 538, in <module> _Main(sys.argv[1:]) File "E:\LocalProject\Oreo\.repo\repo/main.py", line 512, in _Main result = repo._Run(argv) or 0 File "E:\LocalProject\Oreo\.repo\repo/main.py", line 185, in _Run result = cmd.Execute(copts, cargs) File "E:\LocalProject\Oreo\.repo\repo\subcmds\sync.py", line 823, in Execute project.Sync_LocalHalf(syncbuf, force_sync=opt.force_sync) File "E:\LocalProject\Oreo\.repo\repo\project.py", line 1335, in Sync_LocalHalf self._InitWorkTree(force_sync=force_sync) File "E:\LocalProject\Oreo\.repo\repo\project.py", line 2502, in _InitWorkTree raise GitError("cannot initialize work tree") error.GitError: cannot initialize work tree
從log來看,.repo/repo/project.py是要關注的地方,能夠定位到腳本:
raise GitError("cannot initialize work tree")
其所在的函數爲_InitWorkTreejava
_InitWorkTree完整的代碼以下:linux
def _InitWorkTree(self, force_sync=False): dotgit = os.path.join(self.worktree, '.git') print("dotgit is {0}".format(dotgit)) print(self.gitdir) init_dotgit = not os.path.exists(dotgit) try: if init_dotgit: os.makedirs(dotgit) self._ReferenceGitDir(self.gitdir, dotgit, share_refs=True, copy_all=False) try: self._CheckDirReference(self.gitdir, dotgit, share_refs=True) except GitError as e: if force_sync: try: shutil.rmtree(dotgit) return self._InitWorkTree(force_sync=False) except: raise e raise e if init_dotgit: _lwrite(os.path.join(dotgit, HEAD), '%s\n' % self.GetRevisionId()) cmd = ['read-tree', '--reset', '-u'] cmd.append('-v') cmd.append(HEAD) if GitCommand(self, cmd).Wait() != 0: raise GitError("cannot initialize work tree") self._CopyAndLinkFiles() except Exception: if init_dotgit: shutil.rmtree(dotgit) raise
可是此處並不能給咱們什麼有效信息,因此咱們要進一步繼續分析android
用 repo --trace sync -cdf 將repo的全部動做詳細輸出(這個過程可能會很長,須要咱們耐心等待),會發如今這裏出錯致使:git
: cd E:\LocalProject\Oreo\external\kmod : git read-tree --reset -u -v HEAD 1>| 2>| error: unable to create symlink testsuite/rootfs-pristine/test-loaded/sys/module/btusb/drivers/usb:btusb: File exists
至此,咱們就定位到了問題。github
固然,在不熟悉repo命令的時候,咱們也能夠添加log來了解當前卡在了哪裏。爲了找到當前出錯時,git正在處理哪一個目錄,我在_InitWorkTree
函數中加了2句log信息:apache
print("dotgit is {0}".format(dotgit)) print(self.gitdir)
def _InitWorkTree(self, force_sync=False): dotgit = os.path.join(self.worktree, '.git') print("dotgit is {0}".format(dotgit)) print(self.gitdir) init_dotgit = not os.path.exists(dotgit) try: if init_dotgit: os.makedirs(dotgit) ... ... ...
打印出來的log以下:segmentfault
dotgit is E:\LocalProject\Oreo\external\kmod\.git E:/LocalProject/Oreo/.repo/projects/external/kmod.git
能夠看出當前是在處理E:\LocalProject\Oreo\external\kmod時出了問題。可是因爲log有限,咱們其實並不能真正的瞭解到當前發生了什麼。windows
前面的log是說file沒法建立。緣由是是要建立的文件名字叫usb:btusb,這種命名是明顯違反Windows命名規則的。因此實際上是無解的。
因此我打算先繞過這個問題,先把源碼的其餘部分下載下來,對於這個問題,之後再解決。既然這個項目有問題,那我就先不下載了,不能因小失大嘛。
打開.repo/manifest/default.xmlapp
<!--<project path="external/kmod" name="platform/external/kmod" groups="pdk" />-->
在網上搜了一圈,好像不少網友在windows下下載代碼都遇到了"cannot initialize work tree"的問題。連Microsoft提供的win10下linux子系統的repo都有問題(最後參考連接裏邊有該問題的解決方案)。也是路徑名稱的問題。有興趣的網友能夠本身爬樓研究下。

我此次下載中還遇到了兩次"cannot initialize work tree"這樣的問題
下載「platform/libcore」出錯
error: unable to create file luni/src/test/resources/org/apache/harmony/tests/java/lang/test?.properties: Invalid argument
「test?.properties」這個也是違反了Windows文件命名問題
下載「external/libunwind」出錯
fatal: cannot create directory at 'aux': Invalid argument
這個是文件夾命名爲「aux」出錯,「aux」是Windows設備名文件夾。DOS上使用AUX,是auxiliary device的縮寫,輔助設備,在DOS系統手冊有聲明這是系統標識符的。AUX默認是異步端口的流名字,一般與Console連在一塊兒,屬於標準命名設備,因此不容許你建立使用了系統保留名字的文件,由於文件也屬於流設備。
若是你們想體驗下這個問題,能夠單獨下載這三個項目試試 git clone url

我下載的是android_8.1.0_r17版本的代碼:
repo init -u https://aosp.tuna.tsinghua.ed... -b android_8.1.0_r1
