jenkins pluginManager'现在检查''无法找到有效的证书'错误

Question

我刚刚在Windows机器上安装了一个新的jenkins 2.77实例，运行Java 1.8.0＃60。

我期待有一些默认的插件，但它似乎没有安装实例时创建。

当我去检查可用的插件标签，它读取：

Update information obtained: N/A ago

当我点击了“确认”键，我得到一个错误与以下堆栈跟踪：

基于this post，据我了解，我需要做某种键或ssh配置，但我不清楚所有使用的变量，因为它们适用于这个特定的错误。

我该如何解决这个问题？

更新2017年9月11日：

• 我卸载Java和再装最新的Java，1.8.0＃44。
• 我卸载了Jenkins并删除了Program Files文件夹。
• 我安装詹金斯2.77

这一次在安装向导中，我注意到，通知我说，詹金斯是脱机的页面。

我不确定这是什么意思，因为我可以连接到互联网。无论出于何种原因，詹金斯都不能。

我非常确定，当我最初安装Jenkins时，我看到了这个页面并选择了跳过插件安装。 “Jenkins处于离线状态”的消息很可能与“无法找到有效的证书路径到所请求的目标”有关。

this post似乎有类似的问题。

Answer 1

Jenkins 2.77 changed更新中心（UC）的默认URL使用https://而不是http://。

Jenkins UC使用来自Let's Encrypt的SSL证书，但Let's Encrypt证书所依赖的根证书未添加到Java 8，直到update 101。

将Java安装从8u60升级到至少8u101，它应该按预期工作。
