[英]Failed to resolve: com.google.firebase:firebase-core:9.0.0
I get the following error while upgrading a firebase project from old domain to new google firebase domain.将 firebase 项目从旧域升级到新的 google firebase 域时出现以下错误。
Failed to resolve: com.google.firebase:firebase-core:9.0.0
解析失败:com.google.firebase:firebase-core:9.0.0
I followed the steps mentioned on the Firebase documentation , in the section Add Firebase to your Android Project, topic Available libraries .我遵循了Firebase 文档中提到的步骤,在将 Firebase 添加到您的 Android 项目部分,主题可用库中。
What are my options to resolve this error?我有哪些解决此错误的选项?
As of version 11.2.0
Firebase and Google Play services dependencies are available via Google's Maven Repo .从
11.2.0
版本开始,Firebase 和 Google Play 服务依赖项可通过Google 的 Maven Repo 获得。 You no longer need to use the Android SDK manager to import these dependencies.您不再需要使用 Android SDK 管理器来导入这些依赖项。
In your root build.gradle
file add the repo:在您的根
build.gradle
文件中添加 repo:
allprojects {
repositories {
// ...
maven { url "https://maven.google.com" }
}
}
If you are using gradle 4.0
or higher you can replace maven { url "https://maven.google.com" }
with just google()
.如果您使用的是 gradle
4.0
或更高版本,您可以将maven { url "https://maven.google.com" }
替换为google()
。
The 9.0.0
version of Firebase was built using Google Play services 9.0 and is now available under the new packaging com.google.firebase:*
Firebase
9.0.0
版本是使用 Google Play 服务 9.0 构建的,现在可以在新包装com.google.firebase:*

Error:(30, 13) Failed to resolve: com.google.firebase:firebase-auth:9.6.1
If you ever get this error and you are using Android studio 2.2 that comes with firebase component integrated in it which has libraries version 9.6.0 by default and you are adding the latest dependencies like 9.6.1 .如果您遇到此错误,并且您使用的是集成了 firebase 组件的 Android studio 2.2,默认情况下该组件具有库版本 9.6.0,并且您正在添加最新的依赖项,例如 9.6.1 。 You might need to downgrade
com.google.firebase:firebase-auth:9.6.1
to com.google.firebase:firebase-auth:9.6.0
您可能需要将
com.google.firebase:firebase-auth:9.6.1
降级为com.google.firebase:firebase-auth:9.6.0
Or check the library version of your pre-installed firebase and make sure it is of the same version with the new library you are trying to add or added to your project.或者检查您预安装的 firebase 的库版本,并确保它与您尝试添加或添加到项目中的新库的版本相同。
Tried all the above, use the Firebase Assistant !尝试了以上所有方法,使用Firebase 助手! It is the simplest way to solve this.
这是解决这个问题的最简单方法。 First remove all the dependencies you added to the build.gradle (using the manual method) and then in Android Studio:
首先删除你添加到 build.gradle 的所有依赖项(使用手动方法),然后在 Android Studio 中:
Click Tools > Firebase to open the Assistant window.
It really is as easy as that.真的就是这么简单。
Faced myself and seen several times in comments for similar questions - that even after installing "latest" Google Play Services and Google Repository still having the same issue.面对自己并在类似问题的评论中多次看到 - 即使在安装“最新”的Google Play 服务和Google 存储库后仍然存在相同的问题。
The thing is that they may be latest for your current revision of Android SDK Tools , but not that latest your app build requires.问题是它们可能是您当前版本的Android SDK Tools 的最新版本,但不是您的应用程序构建所需的最新版本。
In such case make sure to install latest version of Android SDK Tools first, and probably Android SDK Platform-tools (both under Tools branch).在这种情况下,请确保首先安装最新版本的Android SDK Tools ,可能还有Android SDK Platform-tools (都在Tools分支下)。 Also please note you may need to go through this several times if you haven't updated for a long time (ie install latest Android SDK Tools and Android SDK Platform-tools , then restart Android SDK Manager, then repeat), since the updates seem to be going through some critical mandatory milestones and you cannot install the very latest if you currently have the revision which is pretty "old".
另请注意,如果您长时间没有更新(即安装最新的Android SDK Tools和Android SDK Platform-tools ,然后重新启动 Android SDK Manager,然后重复),您可能需要多次执行此操作,因为更新似乎正在经历一些关键的强制性里程碑,如果您当前拥有相当“旧”的修订版,则无法安装最新版本。

Need to Update需要更新
Android SDK : SDK Tools -> Support Repository -> Google Repository Android SDK : SDK Tools -> Support Repository -> Google Repository
After updating the Android SDK need to sync gradle build in Android studio.更新 Android SDK 后需要在 Android Studio 中同步 gradle build。
In my case, on top of adding google() in repositories for the project level gradle file, I had to also include it in the app level gradle file.就我而言,除了在项目级 gradle 文件的存储库中添加 google() 之外,我还必须将其包含在应用程序级 gradle 文件中。
repositories {
mavenLocal()
google()
flatDir {
dirs 'libs'
}
}
If all the above methods are not working then change implementation 'com.google.firebase:firebase-core:12.0.0'
to implementation 'com.google.firebase:firebase-core:10.0.0'
in your app level build.gradle file.如果上述所有方法都不起作用,则在您的应用级别 build.gradle 中将
implementation 'com.google.firebase:firebase-core:12.0.0'
更改为implementation 'com.google.firebase:firebase-core:10.0.0'
文件。 This would surely work.这肯定会奏效。

这个 SDK 包括谷歌分析的 Firebase SDK。
Now, to use Google Analytics or a product that recommends adding Google Analytics, you need to explicitly declare the Analytics dependency: com.google.firebase:firebase-analytics or com.google.firebase:firebase-analytics-ktx.
现在,要使用Google Analytics或推荐添加Google Analytics的产品,需要显式声明Analytics依赖:com.google.firebase:firebase-analytics或com.google.firebase:firebase-analytics-ktx。
