当代理禁止关键字ftp时，如何更改Jenkins镜像

Question

当我安装jenkins-plugin之类的＆＃39; git-plugin＆＃39;时，jenkins会将我的请求重定向到镜像 ftp.halifax.rwth-aachen.de 。但我在一个公司代理服务器后面工作，该代理服务器禁止对包含“ftp”字样的URL的请求。

下载jenkins插件时有没有办法选择或禁用镜像？ Jenkins在没有包含＆＃39; ftp＆＃39;。

的网站上安装插件没有问题

以下是jenkins日志视图中的错误：

Answer 1

默认情况下，詹金斯（Jenkins）使用http://updates.jenkins-ci.org/update-center.json作为“负载均衡器” URL，它将您转发到最近的地理镜像json（即http://ftp-nyc.osuosl.org/pub/jenkins/updates/current/update-center.json对我而言）。为此，您可以通过在任意位置（即内部）安装此插件并托管json文件来使用自己的json文件：

Answer 2

我找到了解决方法：

1. 直接从http://mirrors.jenkins-ci.org/plugins/gitlab-plugin/latest/

下载插件

2. 将hpi文件上传到jenkins。有一个 在http://host:8080/pluginManager/advanced上传字段。

但这只是一种解决方法。我想得到一个问题的答案：＆＃34; 在为jenkins下载插件时是否有办法选择或禁用镜像？＆＃34;
