问题描述

我在运行Jenkins的Windows 10机器上更新了Git版本，试图解决Git LFS新文件无法下载的问题。更新后，「Scan Multibranch Pipeline」执行git fetch时卡住，创建的本地缓存仓库始终只有25.7 KB（包含19个文件和9个文件夹），未下载任何远程文件。扫描流水线日志如下：

已尝试更换凭证，问题依旧。请问如何获取更多相关信息或日志？

获取更多诊断信息的方法

提升Jenkins Git插件日志级别
进入Jenkins的「Manage Jenkins」→「System Log」→「Add new log recorder」，创建新日志记录器，添加以下类别并设置级别为FINEST：
- org.jenkinsci.plugins.gitclient
- hudson.plugins.git
  重新触发分支扫描，日志会输出Git客户端执行的详细交互过程。
手动在Jenkins服务器执行Git命令
登录Windows 10机器，打开命令提示符，切换到Jenkins缓存仓库目录（C:\Program Files (x86)\Jenkins\caches\git-13907a292e8cd0afde55a9f2fc947755），执行：
```
git fetch --tags --progress origin +refs/heads/*:refs/remotes/origin/* --verbose
```
--verbose参数会输出fetch的详细过程，可查看是否卡在特定对象下载、认证或LFS操作环节。同时执行git config --list确认LFS配置是否正确。
配置Jenkins全局Git调试参数
进入「Manage Jenkins」→「Global Tool Configuration」→「Git」，在「Git executable」的「Additional behaviour」中添加参数，比如-c lfs.loglevel=debug，分支扫描时会传递该参数给Git，输出更多LFS相关日志。
检查Windows系统事件日志
打开Windows「事件查看器」，查看「Windows日志」→「应用程序」中Git或Jenkins相关的错误/警告，排查系统层面问题（如权限、网络连接异常）。
临时延长分支扫描超时时间
在多分支流水线配置中找到「Branch indexing」的超时设置，或在Git插件配置中调整命令超时。若fetch能完成，可查看完整执行日志；若仍卡住，可排除临时网络波动因素。
