Question

我正在更新Android项目中的Firebase和Google Play服务。这就是我更新依赖项的方式：

//Play Services
implementation 'com.google.android.gms:play-services-maps:16.0.0'
implementation 'com.google.android.gms:play-services-gcm:16.0.0'
implementation 'com.google.android.gms:play-services-location:16.0.0'
implementation 'com.google.android.gms:play-services-measurement-base:16.0.5'
implementation 'com.google.maps.android:android-maps-utils:0.5'

//Firebase
implementation 'com.google.firebase:firebase-core:16.0.5'
implementation 'com.google.firebase:firebase-messaging:17.3.4'
implementation 'com.google.firebase:firebase-config:16.1.0'
implementation 'com.onesignal:OneSignal:3.10.3'

当我构建项目时，它失败并出现以下错误：

Failed to resolve: com.google.android.gms:play-services-maps:17.3.4
Failed to resolve: com.google.android.gms:play-services-gcm:17.3.4
Failed to resolve: com.google.android.gms:play-services-location:17.3.4
Failed to resolve: com.google.android.gms:play-services-measurement-base:17.3.4
Failed to resolve: com.google.firebase:firebase-core:17.3.4
Failed to resolve: com.google.firebase:firebase-config:17.3.4
Failed to resolve: com.google.android.gms:play-services-basement:17.3.4
Failed to resolve: com.google.android.gms:play-services-tasks:17.3.4
Failed to resolve: com.google.firebase:firebase-common:17.3.4
Failed to resolve: com.google.firebase:firebase-iid:17.3.4
Failed to resolve: com.google.firebase:firebase-measurement-connector:17.3.4
Failed to resolve: com.google.android.gms:play-services-base:17.3.4

由于某种原因，所有库都需要版本17.3.4。如何运作？

根gradle文件如下所示：

buildscript {
    ext.kotlin_version = '1.3.10'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.2.0'
    }
}

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

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

Answer 1

我以前曾经遇到过OneSignal和依赖项的问题（例如dependency conflict with itself）。我建议回滚到该库的早期版本，并查看是否是最近的问题。

您是否还可以尝试将mavenCentral()添加为存储库，因为它（至少在以前是托管在此存储库中的）。

Answer 2

我将OneSignal插件移到了插件的顶部，由于某种原因它有所帮助。

apply plugin: 'com.onesignal.androidsdk.onesignal-gradle-plugin'
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'

出于某种原因，在google库中，它要求所有版本都相同，因此它需要较高的版本，并尝试在所有其他库中获取相同的版本。

您需要降级其他库并将它们全部置于相同的版本，然后它才能工作。
