无法解析：com.google.android.material：material：1.0.0-alpha1 [英] Failed to resolve: com.google.android.material:material:1.0.0-alpha1

问题描述

所以我按照官方文件的规定将材料组件库添加到我的项目中 https://github.com/material-components/material-components-android/blob/master/docs/getting-started.md

So I'm following the official documentation to add the Material Components library to my project https://github.com/material-components/material-components-android/blob/master/docs/getting-started.md

但它引发以下错误
无法解析：com.google.android.material：material：1.0.0-alpha1

But it throws me the following error "Failed to resolve: com.google.android.material:material:1.0.0-alpha1"

我尝试安装Android Studio建议无法使用的存储库和同步项目。

I've tried installing the repository and sync project that Android Studio suggest to no avail.

我的项目配置

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.2'


    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    classpath 'com.google.gms:google-services:3.2.1'
}
}

allprojects {
repositories {
    google()
    jcenter()
    maven {
        url "https://maven.google.com"
    }
}


task clean(type: Delete) {
delete rootProject.buildDir
}

和应用程序配置

apply plugin: 'com.android.application'

android {
compileSdkVersion 27
defaultConfig {
    applicationId "mlluell.eftremp"
    minSdkVersion 21
    targetSdkVersion 27

推荐答案

现在我已经开始了，我会分享一些解决这个问题的方法。

Thought I'd share what fixed this for me now that I|O has started.

我的初始设置和你一样。为了让它工作，我必须改变以下内容：

I had about the same initial setup as you. To get it working I had to change the following:

• compileSdkVersion to 'android -P'
• 支持库至 '28 .0.0-alpha1'


• include api'com.android.support：design：28.0.0-alpha1'在依赖关系块中。


• SDK平台更新 - Android P预览（最新版）


• targetSdkVersion 'P'

• compileSdkVersion to 'android-P'
• Support Libraries to '28.0.0-alpha1'
• include api 'com.android.support:design:28.0.0-alpha1' in the dependencies block.
• SDK Platform update - Android P Preview (latest)
• targetSdkVersion 'P'

然后，我做了仪式化的'Invalidate Caches / Restart'并重建项目以获得更好的效果。

I then did the ritualistic 'Invalidate Caches / Restart' and rebuilt the project for good measure.
