【中文标题】找不到 com.google.firebase:firebase-analytics-ktx:。要求:项目:app【英文标题】:Could not find com.google.firebase:firebase-analytics-ktx:. Required by: project :app 【发布时间】:2021-02-25 12:40:37 【问题描述】:

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'.

     Required by:

有人知道如何解决这个问题吗?谢谢

【问题讨论】:

如果您想将 Firebase 分析添加到您的 Flutter 应用中,您应该按照文档中的说明进行操作。这不涉及更改 build.gradle - 为此有颤振插件。 firebase.google.com/docs/flutter/setup 【参考方案1】:

尝试替换这个dep

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

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

【讨论】:

【参考方案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")

【讨论】:

谢谢,将平台放在括号内是缺失的部分。 它救了我——实现平台("com.google.firebase:firebase-bom:28.4.1") 轰隆隆!这对我有用。谢谢!【参考方案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。

通过https://firebase.google.com/docs/android/learn-more#bom了解更多信息

【讨论】:

【参考方案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')

【讨论】:

是的,它是这样工作的!
