Jenkins 插件列表无法更新

Jenkins 插件列表无法更新

我在笔记本电脑上安装了 Jenkins,但无法更新插件列表。我只是不知道如何进一步调查。

以下是一些信息:

  • 我的笔记本电脑有 Windows 系统。
  • 我创建了一个安装了 CentOS7 的 VirtualBox VM。
  • VM 有两个网络适配器:一个设置为 NAT(用于访问互联网),另一个设置为仅主机(用于通过 SSH 连接到该 VM)。默认路由设置在 NAT 适配器上。
  • 我在公司代理后面工作,因此我在 Jenkins 插件管理器的“高级”选项卡中设置了代理信息。当我输入“https://www.google.com' 进入“测试网址”框并单击“验证代理”,它显示“成功”但是当我单击页面底部的“立即检查”时,什么也没有发生,它总是显示“获得的更新信息:N/A 前”。
  • 我能够使用 curl 从我的虚拟机中获取“更新站点”中 URL 后面的 JSON 数据(即,我能够在我的虚拟机上成功运行此命令并获取 JSON:curl'https://updates.jenkins.io/current/update-center.json')
  • 我的JRE是从Oracle官方网站下载的最新版本,版本为1.8.0_171 64位(jre-8u171-linux-x64.rpm)。
  • 我的Jenkins是从Jenkins官方网站下载的最新版本(jenkins-2.107.3-1.1.noarch.rpm)

是否有任何 Jenkins 日志可以帮助我检查此问题?

我的 CentOS 上的路由:

[root@localhost ~]# ip route
default via 10.0.2.2 dev enp0s3  proto static  metric 100
10.0.2.0/24 dev enp0s3  proto kernel  scope link  src 10.0.2.15  metric 100
192.168.56.0/24 dev enp0s8  proto kernel  scope link  src 192.168.56.80  metric 100

服务器最终显示以下异常:

如果你检查以下位置的系统日志:Jenkins | 管理 Jenkins | 系统登录所有 Jenkins 日志,成功的尝试应该报告类似以下内容:

Mar 27, 2019 8:49:33 AM INFO hudson.util.Retrier start
Attempt #1 to do the action check updates server
Mar 27, 2019 8:49:37 AM INFO hudson.model.UpdateSite updateData
Obtained the latest update center data file for UpdateSource default
Mar 27, 2019 8:49:40 AM INFO hudson.model.DownloadService$Downloadable load
Obtained the updated data file for hudson.tools.JDKInstaller
Mar 27, 2019 8:49:40 AM INFO hudson.util.Retrier start
Performed the action check updates server successfully at the attempt #1

如果您看到其他内容,请考虑提高日志记录级别。

另外,我配置的更新站点是: https://updates.jenkins.io/update-center.json
