android - 如何获得正确的依赖版本

问题描述

我试图在我的应用程序中实现云 Firestore 数据库。Firestore 仍处于测试阶段，我不知道它需要什么版本，所以我只是复制了与 firebase-core 相同的版本。同步后，我得到了很多错误，我一直在玩这些版本，直到只剩下一条错误消息。它建议我应该将我的 com.google.gms:google-services 版本更改为最新版本。所以这就是我所做的。现在我收到此错误消息：

Error:In project 'app' a resolved Google Play services library dependency depends on another at an exact version (e.g. "[15.0.
1]", but isn't being resolved to that version. Behavior exhibited by the   library will be unknown.
Dependency failing: com.google.android.gms:play-services-flags:15.0.1 -> com.google.android.gms:play-services-basement@[
15.0.1], but play-services-basement version was 16.2.0.

The following dependencies are project dependencies that are direct or have transitive dependencies that lead to the art
ifact with the issue.
-- Project 'app' depends onto com.google.android.gms:play-services-maps@16.1.0
-- Project 'app' depends onto com.google.firebase:firebase-firestore@19.0.0
-- Project 'app' depends onto com.firebaseui:firebase-ui-database@2.1.1
-- Project 'app' depends onto com.google.firebase:firebase-storage@17.0.0
-- Project 'app' depends onto com.google.firebase:firebase-auth@16.0.1
-- Project 'app' depends onto com.google.firebase:firebase-core@16.0.9
-- Project 'app' depends onto com.google.android.gms:play-services-auth@16.0.1
-- Project 'app' depends onto com.google.firebase:firebase-database@17.0.0

For extended debugging info execute Gradle from the command line with ./gradlew --info :app:assembleDebug to see the dep
endency paths to the artifact. This error message came from the google-services Gradle plugin, report issues at https://
github.com/google/play-services-plugins and disable by adding "googleServices { disableVersionCheck = false }" to your b
uild.gradle file.

所以现在我在想我的依赖版本到处都是。我从来没有真正了解过它们，我需要一些帮助来整理它们。这是我的 gradle 文件

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

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'


    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    classpath 'com.google.gms:google-services:4.2.0'
}
}

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

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

apply plugin: 'com.android.application'

android {

解决方案

转到构建 -> 编辑库和依赖项。将打开一个新窗口。您会在右上角找到“+”符号，单击它并在搜索栏中输入关键字，然后按 Enter。您只需从搜索结果中选择所需的库依赖项即可。让我知道这是否有帮助。
