Question

我正试图通过Jenkins从git获取最新代码。每次我这样做，我得到以下错误。我已经跟进了stackoverflow敌人的一些链接，但他们似乎都没有解决这个问题。

尝试删除整个工作区，然后重新运行。它会引发同样的错误。
在执行shell构建选项

这是错误。

Answer 1

我相信你这里有两个问题。

第一个：

Command "C:\Program Files\Git\bin\git.exe read-tree -mu HEAD" returned 
status code 128:
stdout: 
stderr: fatal: Not a valid object name HEAD

实际上相对无害。我们遇到了同样的问题。这是因为读取树调用是在结账之前完成的。结账后设置ref HEAD。在我们的案例中这个错误没有引起任何进一步的问题。我们设法通过在结账前不执行完全擦除来摆脱这一个，但只是干净。

真正的问题是第二个错误：

Caused by: hudson.plugins.git.GitException: Command "C:\Program Files\Git\bin\git.exe checkout -f bc304892eadfaaf7338fa6e5f370137555d7cfd9"     returned status code 128:
stdout: 
stderr: error: Sparse checkout leaves no entry on working directory

我们也遇到了这个问题。在我们的例子中，这是由稀疏结账中的错误路径引起的。仔细检查您输入的路径是否正确。

Answer 2

如果看到一个Not a valid object name HEAD错误，但是git symbolic-ref HEAD的输出似乎很好（例如refs/heads/master），则可能的原因是所使用的Git版本之间不匹配，例如本地计算机上的Git位于2.x，但是远程计算机仍处于1.x。随时随地更新您的Git安装，以摆脱该特定问题。

如何解决stderr：fatal：在jenkins中不是有效的对象名称HEAD？
