将FireBase库更新为16.0.0会引发Google Play Services依赖性问题

直到有一天,我的项目一直运行良好,因为没有任何原因(我没有改变任何东西),Gradle开始给出这个奇怪的错误:

Program type already present: com.google.android.gms.internal.measurement.zzabo

出现此错误时,我的项目级Gradle如下所示:

buildscript {
    repositories {
        jcenter()
        maven {
            url 'https://maven.google.com'
            // Alternative URL is 'https://dl.google.com/dl/android/maven2/'
        }
        maven { url 'https://plugins.gradle.org/m2/'}
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
        classpath 'com.google.gms:google-services:4.0.0'
        classpath 'io.fabric.tools:gradle:1.25.3'
        classpath 'gradle.plugin.com.onesignal:onesignal-gradle-plugin:0.8.1'
    }
}

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

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

这是我的应用程序级毕业生:

apply plugin: 'com.android.application'

我找了找 this 在StackOverflow上应答。这说明这个问题可能与FireBase依赖版本和谷歌服务插件有关。所以我更新了 google-services 插件版本到 4.0.0 和FireBase的最新版本 16.0.0 . 正如人们从Gradle可以预料到的,它给出了另一个错误,似乎与FireBase版本16.0.0有关。

每当我将FireBase版本更改为16.0.0时,显然它也试图自动将Google Play服务依赖项升级为16.0.0。根本不存在!它引发以下渐变错误:

我试图使用解决策略强制使用GMS库的版本,但没有效果。我该怎么办?我做错什么了?

注意:我没有明确更改PlayServicesLibraries的版本,Gradle似乎是因为FireBase才这么做的。

编辑: 这个问题可以通过下面给出的解决方案来解决 this 问题,但仍然不重复,因为在我的例子中,OneSignal插件只是更新 GMS 库版本与否 火碱 版本。所以任何面临这个问题的人都不会搜索 这 问题。
