How to fix issues with NoClassDefFoundError: Failed resolution of: Lcom/google/android/gms/common/R$string on Android

Question

最近，我遇到了一个问题，我一周都无法解决，阅读了不同的资源和建议。但是，没有任何帮助。

所以，问题出在升级后出现的NoClassDefFoundError：

Gradle 从 5.x 到 6.x
Gradle 构建工具
Firebase 依赖项（它们实际上带来了这些类我有问题）

我已经尝试解决的问题：

试图降级 Firbase 库（我只有核心、广告和分析）
试图禁用传递basemenet依赖
尝试应用 BOM 来同步依赖项
尝试 upgrade/downgrade android 构建插件
试图找出现有 green-dao 版本的问题，但看起来不错

这是我的 build.gradle 文件中的依赖项：

也许这是一个常见的问题，但我不知道如何处理它。

谢谢

Answer 1

所以，经过几天的挖掘，我找到了解决方案。所以，为了让它发挥作用，我必须：

将AndroidGradle插件降级到3.5.3版本
将Gordon插件降级到1.0.6版本
已将 fabric-crashlytic 迁移到 firebase-crashlytic。加上最后一个插件，否则会出错

所有其他更新都可以设置，但这3项必须坚持提到的版本。
