BUILD FAILED in 6s

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

ai说明问题是

Plugin with id 'com.android.application' not found.

这是说Gradle找不到com.android.application这个插件，导致构建失败。这个问题一般是Android Gradle插件没有正确配置或者环境不完整引起的。

但是我几个月前还能成功打包出来，经过查阅发现是之前搞大作业，c盘不知道怎么弄的.gradle文件夹和unity的.gradle文件夹冲突了。

解决办法就是把c盘用户文件夹下的.gradle删除（一定要先重启再删除，这样才删的掉）

最后成功解决了问题，打包出来了项目。
