我正在尝试为我的应用构建gradle，但是构建失败
我试图更改gradle版本号和gradle插件版本号，但是每次我遇到愚蠢的错误时，我都不知道为什么！我尝试根据此doc进行了更改
gradle 5.6.4 >>> gradle插件版本3.6.3
gradle 5.6.4 >>> gradle插件版本3.6.0
gradle 5.6.4 >>> gradle插件版本3.4.0
gradle 5.6.2 >>> gradle插件版本3.6.0
gradle 5.6.2 >>> gradle插件版本3.5.0
并且列表继续，但是每次我说相同的错误：
* What went wrong:
A problem occurred evaluating project ':app'.
> com/google/common/util/concurrent/SettableFuture
我尝试根据此question进行更改 帮助导致我最近3天因为这个错误而遇到麻烦，并且我是新手。 当前数字是：
distributionUrl=https\://services.gradle.org/distributions/gradle-5.6.4-all.zip
classpath 'com.android.tools.build:gradle:3.6.3'
谢谢
这是抖动-v
