我正在尝试将 Firebase crashlytics 添加到现有项目(不是我开发的)。我不断收到错误

ERROR: Could not find com.google.gms.google-services:4.2.0:.
Required by:
    project :
Search in build.gradle files

我已经完成了要求添加 maven { url ' https://maven.google.com 的所有(或大部分)解决方案' } 并且它们都不起作用。对于所有解决方案，我都收到上述错误。

请不要让我开发的其他项目使用相同的 build.gradle 工作正常，但不确定为什么这个项目给我带来噩梦。

project level build.gradle

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

buildscript {

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

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.2'
        // Check for v3.1.2 or higher
        classpath 'com.google.gms.google-services:4.2.0'

        // Add dependency
        classpath 'io.fabric.tools:gradle:1.28.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

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

    }
}

apply plugin: 'com.google.gms.google-services'

最佳答案

您在 classpath 语句中有错字。

这个

classpath 'com.google.gms.google-services:4.2.0'

应该是

classpath 'com.google.gms:google-services:4.2.0'

关于android - 错误 : Could not find com. google.gms.google-services :4. 2.0，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55416111/
