Searched in the following locations: - file:/G:/myproject/study/Plugin-Demo/myapplication/libs/recyclerview-1.0.0.jar - file:/G:/myproject/study/Plugin-Demo/myapplication/libs/recyclerview.jar Required by: ```  **解决方案：在项目根目录的 build.gradle 文件中添加以下内容：** ``` allprojects { repositories { google() jcenter() } } ``` [1]: https://nativesupport.dcloud.net.cn/AppDocs/download/android "官方原生插件开发案例"
