所以我更新了build.gradle文件：
compile 'com.android.support:appcompat-v7:23.0.1' compile 'com.android.support:recyclerview-v7:23.0.1' compile 'com.android.support:cardview-v7:23.0.1' compile 'com.android.support:design:23.0.1'
但当我尝试同步项目时,会弹出
Error:(25,13) Failed to resolve: com.android.support:recyclerview-v7:23.0.1 Install Repository and sync project Show in File Show in Project Structure dialog
(和其他两个存储库相同)
然后我尝试单击“安装存储库并同步项目”,并发生以下错误：
Ignoring unknown package filter 'extra-android-m2repository'Warning:
The package filter removed all packages. There is nothing to install.
Please consider trying to update again without a package filter.
并安装失败.
我已经在SDK管理器中安装了构建工具23.0.1以及android M的所有内容.
尝试回滚到23.0.0,但它是一样的.
怎么了？这个包过滤器来自哪里？在发生此错误之前,我不认为我更改了除build.gradle之外的任何内容
编辑：我试图删除构建工具并再次安装它们,同时安装SDK管理器日志弹出：
