新建了一个测试项目，准备使用Glide测试一些东西，但是却报错。

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
根据日志看是引用冲突问题，用了排除依赖的方法依然不行。
进入Glide的Github地址：
https://codechina.csdn.net/mirrors/bumptech/glide?utm_source=csdn_github_accelerator
看到最新版本是12，所以就更新版本到4.12.0就可以了。
