Can't install

default.json

google replaced baidu

updates.jenkins-ci.org replaced with mirrors.tuna.tsinghua.edu.cn

Some plugins can be installed, and there are still plugins that cannot be installed and it is very slow!

In Chinese:

安装不了

default.json 

google 替换了 baidu

updates.jenkins-ci.org 换成了 mirrors.tuna.tsinghua.edu.cn

可以安装部分插件了，还是有安装不了的插件而且慢的很！
