问题描述
尝试使用 FireStore 和 Google 身份验证创建一个简单的应用程序.gradle 有问题:
Trying to create a simple app with FireStore and Google Authentication. Having problem with the gradle:
在项目app"中,解决了 Google Play 服务库依赖项取决于另一个确切版本(例如[15.0.1]",但不是正在解决该版本.图书馆展示的行为将不为人知.
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.
依赖失败:com.google.android.gms:play-services-flags:15.0.1-> com.google.android.gms:play-services-basement@[15.0.1],但 play-services-basement 版本是 16.0.1.
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 16.0.1.
以下依赖项是直接或直接的项目依赖项具有传递依赖关系,导致艺术 ifact 与问题.-- 项目 'app' 依赖于 com.google.firebase:firebase-firestore@17.1.5-- 项目 'app' 依赖于 com.firebaseui:firebase-ui-auth@4.2.0
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.firebase:firebase-firestore@17.1.5 -- Project 'app' depends onto com.firebaseui:firebase-ui-auth@4.2.0
对于扩展调试信息,从命令行执行 Gradle./gradlew --info :app:assembleDebug 查看依赖路径神器.此错误消息来自 google-services Gradle插件,在 https://报告问题github.com/google/play-services-plugins 并通过添加禁用googleServices { disableVersionCheck = false }"到您的 b uild.gradle文件.
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.
apply plugin: 'com.android.application' android { compileSdkVersion 27 defaultConfig { applicationId "myapp.com" minSdkVersion 19 targetSdkVersion 27 versionCode 11 versionName "1.1" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" multiDexEnabled true } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } } } dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support:appcompat-v7:27.1.1' implementation 'com.android.support.constraint:constraint-layout:1.1.3' testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.2' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' implementation 'com.google.firebase:firebase-firestore:17.1.5' implementation 'com.firebaseui:firebase-ui-auth:4.2.0' } apply plugin: 'com.google.gms.google-services' com.google.gms.googleservices.GoogleServicesPlugin
项目等级:
buildscript { repositories { google() jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.2.1' classpath 'com.google.gms:google-services:4.2.0' } }
有人可以帮帮我吗?
推荐答案
这里有很多解决方案的答案,这些解决方案并没有真正解决问题.以下是解决此问题的一般方法:
There are many answers here for individual solutions that do not really get down to the problem. Here is how to solve this in general:
正如原始日志输出所示,使用以下命令在终端中运行构建很有用:
As the original log output suggests, it is useful to run the build in the terminal with the following command:
./gradlew --info assembleDebug
这将为您提供冲突中涉及的所有依赖项的列表.它看起来与此类似(我删除了包名称以使其更具可读性):
This will give you a list of all dependencies that are involved in the conflict. It looks similar to this (I removed the package name stuff to make it a bit more readable):
Dependency Resolution Help: Displaying all currently known paths to any version of the dependency: Artifact(groupId=com.google.firebase, artifactId=firebase-iid) -- task/module dep -> firebase-analytics@17.2.0 ---- firebase-analytics:17.2.0 library depends -> play-services-measurement-api@17.2.0 ------ play-services-measurement-api:17.2.0 library depends -> firebase-iid@19.0.0 -- task/module dep -> firebase-core@17.2.0 ---- firebase-core:17.2.0 library depends -> firebase-analytics@17.2.0 ------ firebase-analytics:17.2.0 library depends -> play-services-measurement-api@17.2.0 -------- play-services-measurement-api:17.2.0 library depends -> firebase-iid@19.0.0 -- task/module dep -> play-services-measurement-api@17.2.0 ---- play-services-measurement-api:17.2.0 library depends -> firebase-iid@19.0.0 -- task/module dep -> firebase-iid@19.0.0 -- task/module dep -> firebase-messaging@17.1.0 ---- firebase-messaging:17.1.0 library depends -> firebase-iid@[16.2.0] -- task/module dep -> com.pressenger:sdk@4.8.0 ---- com.pressenger:sdk:4.8.0 library depends -> firebase-messaging@17.1.0 ------ firebase-messaging:17.1.0 library depends -> firebase-iid@[16.2.0]
从这个列表中你会知道两件事:
From this list you get to know 2 things:
- 在哪里发现了相互冲突的依赖关系
- 设置了哪些版本的冲突依赖项
在我的情况下,冲突的依赖是 firebase-iid:它是 @19.0.0 或 @16.2.0
In my case the conflicting dependency is firebase-iid: It's either @19.0.0 or @16.2.0
要解决此问题,您必须在 build.gralde 中明确定义错误 firebase-iid 的顶级依赖项.
To fix this you must define the top-level dependency of the wrong firebase-iid explicitly in your build.gralde.
所以在上面的日志中,您可以看到有 2 个过时版本的 firebase-iid@16.2.0 示例.一个来自 --task/module dep ->firebase-messaging@17.1.0 来自第三方库(pressenger)的另一个.我们对第三方库没有影响,所以这里无所谓.但是对于其他依赖项,我们必须使用正确的版本显式声明它:
So in the upper log you can see that there are 2 examples of an out-dated version of firebase-iid@16.2.0. One comes from -- task/module dep -> firebase-messaging@17.1.0 the other one from a third-party library (pressenger). We don't have influence on the third-party library, so nothing to do here. But for the other dependency, we have to declare it explicitly with the correct version:
实现 'com.google.firebase:firebase-messaging:20.0.0'
现在构建再次运行.快乐的结局:)
Now the build works again. Happy ending :)
