我在Windows Server 2025上把Jenkins作为服务运行。

我的Jenkinsfiles与我的共享库也存放在同一个GitLab仓库中。

手动构建任意一个流水线时一切正常，但当流水线A 调用流水线B 时，会出现如下错误：

如果手动执行git命令，我没有看到任何错误。

在网上查找后，我尝试了以下解决方案：

• 在HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem中启用Windows长路径
• 为Git启用长路径（core.longpaths=true）
• 将Jenkins的 home目录移动到驱动器根目录以缩短路径
• 将流水线移动到Jenkins根目录（无子文件夹）以缩短路径

尽管做了这些改动，问题仍然存在。

Jenkins版本：2.555.1（最新）

Git插件版本：5.10.1（最新）

解决方案

最终通过在Jenkins工具中添加JGit找到了一个解决方案：

在Manage Jenkins > Tools > Git installations > + Add Git > JGit中添加JGit。

JGit是纯Java，因此Jenkins不需要运行Git.exe。

注：如果你使用带有遗留SCM的共享库，你需要在库定义中强制使用JGit（Manage Jenkins > System）。
