Android Studio在 dependencies 块下添加recyclerview依赖出现错误Error:unable to resolve dependency for ':app@debug/compileClasspath':Could not resolve androidx.recyclerview:recyclerview:1.1.0.

Question

在dependencies块里添加其它的依赖都会报错，有没有大佬知道这是为什么啊，这个已经折磨我一个星期了T T..

gradle 是不是选了 offline，或者写了代理，也有可能你是以前在host做了些什么修改

最好加上淘宝的源试试

buildscript {
    repositories {
        maven{ url 'http://maven.aliyun.com/nexus/content/groups/public/'}
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        maven { url 'http://maven.aliyun.com/nexus/content/groups/public/' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/jcenter' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/google' }
        maven { url 'http://maven.aliyun.com/nexus/content/repositories/gradle-plugin' }
        google()
        jcenter()

    }
}
