我的Jenkins安装（1.442，升级不是一个选项，因为它是公司管理的中央安装）需要访问代理后面的SVN存储库（通过https）。我相应地配置了.subversion/servers文件，并设置了http_proxy和https_proxy个环境变量。
SVN连接从根本上起作用：
但是，每当由于repo的更改而触发构建时（或者如果我在Jenkins工作区中尚未存在SVN更新时手动触发构建），则会发生以下错误。当Jenkins在SVN中检测不到任何更改时，构建工作，因此不会尝试构建更改日志。
预计Jenkins机器无法解析主机名，但绝不应该尝试使用代理。
对我来说，这看起来好像Jenkins SVN插件正确地使用代理配置从SVN进行轮询和更新，但是SVN更改日志构建器忽略了该配置？！
任何提示如何解决这个问题？

答案 0 :(得分：0)
我终于能够解决这个问题了。
事实证明，SVN轮询和签出发生在分配作业的Jenkins从站上，而更改日志构建步骤发生在Jenkins主站上。
果然我们只在奴隶上安装了SVN代理服务器......
