android - 无法将 Firestore 添加到我的项目中

转载作者：行者123 更新时间：2023-12-05 00:12:38

当我尝试将 firestore 添加到我的项目时。它开始向我显示依赖项错误。我尝试更改与同一版本相关的每个 firebase 的版本。它显示无法下载 .jar 文件。有人帮助我解决这个问题。我包含了 maven url 也没有用....enter code here

我不知道如何手动添加这些 jar 文件。有什么办法可以解决这个问题。以便自动下载这些文件。提前致谢

错误:

最佳答案

我已将 mavenCentral() 添加到项目级别的 build.gradle 文件中。Gradle 同步成功。

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

buildscript {
    repositories {
        google()
        jcenter()
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.1'
        classpath 'com.google.gms:google-services:4.2.0'

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

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()    }
}

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