Question

我们只在 CI 上看到一个奇怪的错误。我们有一个 git 存储库（我们称之为“OUTER”），其中包含一个子模块（“INNER”）。如果我们在开发机器上正常克隆“OUTER”并更新子模块，我们不会发现任何问题。在 CI 上，Bitrise 以奇怪的方式“克隆”存储库后，git fetch在尝试获取子模块时调用会抛出错误。

\n

这是一个示例输出。请注意，前几行模拟 Bitrise 如何“克隆”存储库。

使用GIT_TRACE=2和--verbose产生以下输出：

我不知道从哪里来57df880c914a482c26a1db9b388a34ee55e22730。我在任何地方都找不到任何关于它的参考，但我可能不知道去哪里找。有什么帮助吗？

Answer 1

57df880c914a482c26a1db9b388a34ee55e22730来自超级项目（引用子模块的存储库）中的提交。您的git fetch操作正在“递归”模式下运行，它尝试使用超级项目中的指令git fetch在每个子模块中运行。不幸的是，超级项目中的指令要么完全错误，要么远程（子模块最初克隆的位置）上的Git 软件无法理解。

正如您在自己的评论中指出的那样，git fetch --no-recurse-submodules避免尝试运行该特定提交的递归获取。您还可以默认配置递归关闭，使用git config fetch.recurseSubmodules false. 将其设置为on-demand此处可能有效也可能无效。
