Firebase 和 Play-Services 之间的另一个版本冲突：com.google.android.gms:play-services-measurement-base答案

【问题标题】：Another version conflict between Firebase and Play-Services: com.google.android.gms:play-services-measurement-baseFirebase 和 Play-Services 之间的另一个版本冲突：com.google.android.gms:play-services-measurement-base
【发布时间】：2018-09-12 11:07:27
【问题描述】：

我的应用使用部分 Google Play 服务和 Firebase，我想实现 Firebase 的应用内消息。我的 google-services 插件在 v4.1.0，我的应用级 Gradle 文件中的相关依赖项如下所示：

implementation "com.google.android.gms:play-services-location:15.0.1"
implementation "com.google.android.gms:play-services-analytics:16.0.3"
implementation "com.google.android.gms:play-services-ads:15.0.1"
implementation "com.google.android.gms:play-services-auth:16.0.0"
implementation 'com.google.firebase:firebase-inappmessaging-display:17.0.1' //this error only popped up when I added this line
implementation 'com.google.firebase:firebase-messaging:17.3.1'
implementation "com.google.firebase:firebase-core:16.0.3"
implementation "com.google.firebase:firebase-auth:16.0.3"
implementation "com.google.firebase:firebase-database:16.0.2"
implementation "com.google.firebase:firebase-config:16.0.0"
implementation "com.google.firebase:firebase-appindexing:16.0.1"

我在尝试构建我的应用时遇到以下错误：

The library com.google.android.gms:play-services-measurement-base is being requested by various other libraries at [[15.0.4,15.0.4], [16.0.2,16.0.2]], but resolves to 16.0.2.

我知道一些其他问题和 Firebase 的文档说我必须将所有 Firebase 和 Play 服务的功能更新到最新版本，但这些是最新版本。我已经检查了两者的官方文档。

16.0.2 仅匹配 firebase-database 依赖项，所以与此有关吗？或者是别的什么（缺失或需要更新）？

编辑：根据要求，我的项目级 Gradle 文件：

// Top-level build file where you can add configuration options common to all sub-projects/modules.

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

    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.4'
        classpath 'com.google.gms:google-services:4.1.0' // google-services plugin
    }
}

allprojects {
    repositories {
        jcenter()
        mavenCentral()
        maven {
            //url "https://jitpack.io"
            url "https://maven.google.com"
        }
        flatDir {
            dirs 'libs'

    }
}

还有我的 app 模块级 Gradle 文件：

【问题讨论】：

尝试将firebase-core 放在依赖列表的首位，如相关问题的答案所述：stackoverflow.com/q/51025793/4815718
我认为它不起作用，尽管我确实发现由于某种原因 com.google.firebase:firebase-inappmessaging-display:17.0.1 和 com.google.firebase:firebase-config:16.0.0 一起引起了某种冲突 - 当我删除其中一个时，错误消失了。如何使用:app:dependencies 选项查看导致错误的冲突内容？
要查看依赖关系树，请注释掉 gradle 文件底部的 apply plugin: 'com.google.gms.google-services' 行，然后在终端窗口中输入命令 gradlew :app:dependencies
我无法重现您的结果，尽管我的配置不同。我正在使用google-services:4.0.2 和gradle:3.3.0-alpha10。如果您更新您的问题以包含项目和应用模块的整个 build.gradle 文件，我会再看更多。
有gradle:3.3.0-alpha10？我以为最新的是 3.1.4。

【解决方案1】：

此错误看起来与您尝试在 firebase 中添加的插件有关。

我尝试将 play-services-vision 与 firebase-analytics 一起使用，但我看到了同样的错误。有时它会卡在版本检查上，如果有最新版本的插件（play-services-vision），它就不会构建。

implementation 'com.google.android.gms:play-services-vision:20.1.2' // was 17.0.0
implementation 'com.google.firebase:firebase-analytics:17.5.0'

您可以根据需要禁用它，但始终尝试使用最新版本的插件。

【讨论】：

插件，您是指play-services-vision 和firebase-analytics 依赖项...以及Gradle 插件吗？
