android - 找不到 com.google.firebase :firebase-database: 15. 0.0

Question

我正在使用 React-Native 开发一个应用，并尝试将其连接到我的 Firebase 数据库。当我尝试运行我的代码(即react-native run-android)时，我得到以下信息:

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring project ':app'.
> Could not resolve all dependencies for configuration ':app:_debugApkCopy'.
   > Could not find com.google.firebase:firebase-database: 15.0.0.

我查看了 Could not find com.google.firebase:firebase-database:9.2.0 中提出的解决方案和 react native Could not find com.google.firebase ，但到目前为止都没有为我工作......

这是我的顶级 build.gradle 文件:

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:2.2.3'
    classpath 'com.google.gms:google-services:4.0.0'

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

allprojects {
    repositories {
        mavenLocal()
        jcenter()
        maven {
            // All of React Native (JS, Obj-C sources, Android binaries) is installed from npm
        url "$rootDir/../node_modules/react-native/android"
    }
    maven { url "https://maven.google.com" }
    maven { url "https://jitpack.io" }
    }
}

这是我的应用程序级别 build.gradle 文件的一部分:

dependencies {
compile fileTree(dir: "libs", include: ["*.jar"])
compile "com.android.support:appcompat-v7:23.0.1"
compile "com.facebook.react:react-native:+"  // From node_modules
compile "com.google.firebase:firebase-core:15.0.2"
compile "com.google.firebase:firebase-database: 15.0.0"
compile "com.google.android.gms:play-services-base:15.0.0"

task copyDownloadableDepsToLibs(type: Copy) {
from configurations.compile
into 'libs'
}

apply plugin: 'com.google.gms.google-services'
apply from: "../../node_modules/react-native-vector-icons/fonts.gradle"

如何解决这个问题？谢谢。

您需要更新您的 gradle 和 android 构建插件，将 google() 存储库添加到您的项目 build.gradle。

将 gradle 文件夹中的 gradle-wrapper.properties 更改为:

，将 gradle 版本至少更新到版本 4.4

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

更新构建插件并将 google() 存储库添加到您的 build.gradle 中，以便您的项目 build.gradle 将变成这样:

buildscript {
  repositories {
    jcenter()
    google()
  }
  dependencies {
    // update to version 3.1.3
    classpath 'com.android.tools.build:gradle:3.1.3'
    classpath 'com.google.gms:google-services:4.0.0'

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

allprojects {
    repositories {
        mavenLocal()
        jcenter()

        // the following is the same as google()
        //maven { url "https://maven.google.com" }
        google()
        maven { url "https://jitpack.io" }
    }
}
