找不到 com.google.firebase:firebase-analytics-ktx:。要求：项目：app

Question

我按照在 Firestore 中注册我的移动应用程序的步骤操作，但是当我尝试运行代码时出现以下错误。我在注册我的应用程序时从 firestore 下载了 google services.json 并将其添加到我的项目的 android/app 级别。我还在我的 android/app/build gradle 文件中添加了“com.google.firebase:firebase-analytics-ktx”

FAILURE: Build failed with an exception.

* What went wrong:
Could not determine the dependencies of task ':app:compileDebugJavaWithJavac'.
> Could not resolve all task dependencies for configuration ':app:debugCompileClasspath'.
   > Could not find com.google.firebase:firebase-analytics-ktx:.
     Required by:
         project :app

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

有人知道如何解决这个问题吗？谢谢

Answer 1

尝试替换这个dep

implementation 'com.google.firebase:firebase-analytics-ktx'

与

implementation 'com.google.firebase:firebase-analytics:17.5.0'

Answer 2

我只能像这样让 firebase BoM 与 build.gradle.kts 一起工作：

implementation(platform("com.google.firebase:firebase-bom:28.4.1"))
implementation("com.google.firebase:firebase-analytics-ktx")
implementation("com.google.firebase:firebase-crashlytics-ktx")

Answer 3

您可能希望开始使用材料清单，而不是依赖可能不兼容的不同 Firebase 库的特定版本，例如：

dependencies {
  // Import the BoM for the Firebase platform
  implementation platform('com.google.firebase:firebase-bom:26.5.0')

  // Declare the dependencies for the desired Firebase products without specifying versions
  implementation 'com.google.firebase:firebase-analytics-ktx'
  implementation 'com.google.firebase:firebase-firestore-ktx'
}

Firebase Android BoM（物料清单）使您能够通过仅指定一个版本（即 BoM 版本）来管理所有 Firebase 库版本。

当您在应用中使用 Firebase BoM 时，BoM 会自动提取映射到 BoM 版本的各个库版本。所有单独的库版本都将兼容。当您在应用中更新 BoM 版本时，您在应用中使用的所有 Firebase 库都将更新为映射到该 BoM 版本的版本。

Answer 4

我遇到了类似的问题，在我的情况下，我使用的是 BoM，但我已经声明了 BoM 依赖项

implementation 'com.google.firebase:firebase-bom:28.0.1'  // without platform

而不是

implementation platform('com.google.firebase:firebase-bom:28.0.1')
