Question

这是我的build.gradle：

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }

当我升级此行时：

我收到此错误：

这是build.gradle文件：

// Top-level build file where you can add configuration options common to all sub-projects/modules.
buildscript {
    ext.kotlin_version = "1.3.10"
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.2'
        classpath 'com.google.gms:google-services:4.3.2'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "org.jetbrains.kotlin:kotlin-android-extensions:$kotlin_version"
    }
}

allprojects {
    repositories {
        jcenter()
        flatDir {
            dirs 'libs'
        }

        // For MobFox
        maven {
            url "https://jitpack.io"
        }
        // For AppBrain SDK
        maven {
            url 'http://swisscodemonkeys.github.io/appbrain-sdk/maven'
        }
    }
}

任何想法会导致此重复错误吗？我该如何解决？

Answer 1

您无需检查Document：https://developers.google.com/android/guides/releases就升级了Google Play服务依赖项，它明确表示，对于Google Play服务广告18.0.0，您的项目中需要androidX。因此，现在将您的项目更新为Android X。

选项1：要么使用com.google.android.gms：play-services-ads：17.2.1，否则不建议使用，因为您必须使用最新的依赖项。

或

选项2：转到Android Studio（使用最新的Android Studio）->重构->迁移到AndroidX。压缩/备份您的项目并运行迁移。

Answer 2

在您的gradle.properties中添加

android.useAndroidX=true
android.enableJetifier=true

Answer 3

请尝试重构>迁移到AndroidX ，然后按进行重构

引自official doc，

使用Android Studio 3.2及更高版本，您可以迁移现有的   通过选择“重构”>“迁移到AndroidX”将项目投影到AndroidX   从菜单栏中。

refactor命令使用两个标志。默认情况下，两者   在您的gradle.properties文件中设置为true：

android.useAndroidX=true

Android插件使用适当的AndroidX库，而不是支持库。

android.enableJetifier=true

Android插件会自动迁移现有的第三方库通过重写二进制文件来使用AndroidX。

来自androidx.core：core：1.0.0和com.android.support:support-compat:26.1.0的重复类
