错误：无法解析'：app @ debug / compileClasspath'的依赖关系：无法解析androidx.legacy：legacy-support-v4：1.0.0，为什么？

Question

我真的不知道这个问题是从哪里来的，已经尝试了一段时间。当我执行gradle同步时，我不断收到此错误。

错误：无法解析'：app @ debug / compileClasspath'的依赖关系：无法解析androidx.legacy：legacy-support-v4：1.0.0。

我什至不知道为什么我收到androidx错误，我什至没有迁移到androidx。这正常吗？

我执行了网上发现的各种修复程序，包括将所有依赖项更新到最新版本。下面我发布了我的应用程序和项目gradle文件

我的项目gradle文件：

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.1'
        classpath 'com.google.gms:google-services:4.3.2'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}
allprojects {
    repositories {
//        google()
        jcenter()
        maven { url "https://jitpack.io" }
        google()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

我的应用gradle文件：

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.bahdape.archangels"

            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

您的firebase-ui已移至androidx。您可以在gradle中排除依赖项。
