由于网络原因，Jenkins 插件可能无法正常安装
解决方案：
-
尝试修改更新站点为可用的镜像站点，参考 Jenkins 镜像状态
打开 Jenkins > Manage Jenkins > Manage Plugins > Advanced，将 Update Site 的值由 http://updates.jenkins-ci.org/update-center.json 修改为 https://mirrors.tuna.tsinghua.edu.cn/jenkins/updates/update-center.json
-
手动安装插件
- 访问 https://mirrors.tuna.tsinghua.edu.cn/jenkins/plugins/，下载需要的插件
- 打开 Jenkins > Manage Jenkins > Manage Plugins > Advanced > Upload Plugin，进行插件上传
- 访问 http://xxx.xxx.xxx.xxx:8080/restart，以重启 Jenkins
Jenkins 访问特别慢，且不消耗服务器资源
Jenkins 访问特别慢。CPU、内存、磁盘资源占用特别低。怀疑可能是配置问题。
解决方案：
- 检查 jre 版本是否是 64 位的，如果不是，参考 https://stackoverflow.com/questions/49457923/jenkins-jre-update 进行调整。
- 调整 C:Program Files (x86)JenkinsJenkins.xml 中内存参数
<service>
<!--> ... <!-->
<arguments>-Xrs -Xmx5120m -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle -jar "%BASE%jenkins.war" --httpPort=8080 --webroot="%BASE%war"</arguments>
<!--> ... <!-->
</service>

解决方案：
将 Jenkins 移动到无空格的安装目录
- 停止 Jenkins 服务
- 拷贝 Jenkins 整个文件夹到新的目录，比如 C:Jenkins
- 修改注册表项 HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesJenkinsImagePath 为新的路径
- 启动 Jenkins 服务
