Jenkins构建失败：SVN E175002连接重置错误求助

问题描述 #

Jenkins任务持续构建失败，根源是SVN连接异常（已隐去敏感URL和任务名）。工作区未完整拉取仓库文件，仅获取Python虚拟环境文件夹，完全没有源码文件。尝试过相关讨论方案无效，构建时提示工作区锁定，执行重新获取工作区、清理本地目录操作后，仍出现SVN连接重置、REPORT请求失败的错误。

排查及解决步骤 #

• 手动验证SVN连接
  在Jenkins节点机器上执行命令：svn checkout <你的SVN仓库URL>，确认能否正常拉取代码。若命令行也失败，优先排查：

  • 用ping <SVN服务器地址>或telnet <SVN服务器地址> <端口>测试网络连通性（默认HTTP端口80，HTTPS端口443）
  • 确认SVN服务器运行状态正常，仓库路径无误
  • 测试SVN凭据有效性，执行svn login验证登录权限

• 清理Jenkins工作区与SVN缓存

  1. 进入Jenkins任务页面，点击【工作区】→【删除工作区】，彻底清除旧工作区文件
  2. 找到Jenkins节点的SVN缓存目录（通常为~/.subversion），删除其中的auth、tmp文件夹，清理旧认证信息和临时文件

• 调整Jenkins SVN配置

  • 更换SVN客户端版本：在Jenkins全局工具配置中，尝试切换至不同版本的SVN客户端（如1.9.x或1.14.x）
  • 延长超时时间：在SVN SCM配置的高级选项中，增加连接超时和读取超时的时长
  • 修改更新策略：将更新方式改为【清理后更新】，或直接选择【强制检出】（每次构建重新拉取完整代码）

• 检查网络代理与防火墙

  • 若Jenkins通过代理访问SVN，确认代理配置正确，未拦截SVN的REPORT请求
  • 检查防火墙规则，确保允许Jenkins节点与SVN服务器之间的HTTP/HTTPS通信，尤其是REPORT方法的请求
