Question

我正面临这个问题，我已经做了所有强制性更改，但仍然面临着

build.gradle（项目级别）

buildscript {
    repositories {
        jcenter()
        google()
        maven {
            url 'https://maven.fabric.io/public'
        }
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'io.fabric.tools:gradle:1.25.4'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.1.0'
    }
}

allprojects {
    repositories {
        jcenter()
        google()
        maven { url 'https://jitpack.io' }
        maven { url 'https://maven.google.com' }
    }
}

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

Answer 1

确保所有support lib具有相同的版本。

Answer 2

有多种原因导致您收到此错误，

第一个可能是你的互联网工作不正常，因为我看到你使用了很多第三方库，因此需要高速互联网下载。

第二个可能是您的项目设置处于离线模式通过转到文件 - ＆gt;进行检查。设置 - ＆gt;构建，执行，开发并单击Gradle并查看＆＃34; Offline＆＃34;是否选中了工作复选框。

第三个可能是缓存内存只是无效并重新启动项目转到文件 - ＆gt;使高速缓存/重新启动无效。

希望这个帮助
