amazon-ec2 - 没有可用的插件-Jenkins

Question

我已经在Amazon ec2微型实例上安装了一个新的 Jenkins ，但是当我访问插件管理器时，我没有任何可用的插件。怎么了？

我使用本指南进行安装
https://wiki.jenkins-ci.org/display/JENKINS/Installing+Jenkins+on+Ubuntu

我正在运行ubuntu 11.04 64位和jenkins-war:1.450

查看我的日志文件，我看到了

Answer 1

似乎描述可用插件的Update Center JSON文件可能暂时损坏或未正确下载。

我刚刚尝试立即下载并解析此文件，它看起来还不错，所以我将尝试手动触发更新检查。

转到:管理Jenkins→管理插件→高级，然后单击右下角的立即检查。
