android - 错误:尝试添加多个依赖项时无法解决:com.android

Question

我现在正在学习1.5岁的Udemy指南，我刚刚购买了各种高级android东西。我到了要加载一堆第三方库的地步，所以我按照指南进行操作，并得到以下错误提示:

ERROR: Failed to resolve: com.android
Affected Modules: app


WARNING: The specified Android SDK Build Tools version (26.0.2) is ignored, as it is below the minimum supported version (28.0.3) for Android Gradle Plugin 3.4.1.
Android SDK Build Tools 28.0.3 will be used.
To suppress this warning, remove "buildToolsVersion '26.0.2'" from your build.gradle file, as each version of the Android Gradle Plugin now has a default version of the build tools.
Remove Build Tools version and sync project
Affected Modules: app

这是我的项目级别gradle-

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.4.1'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        google()
        jcenter()

    }
}

ext {
    compileSdkVersion = 28
    buildToolsVersion = '26.0.2'
    minSdkVersion = 23
    targetSdkVersion = 28
    supportLibraryVersion = '26.1.0'
    daggerVersion = '2.11'
    retrofitVersion = '2.3.0'
    moshiVersion = '1.5.0'
    autoValueVersion = '1.5.1'
    autoValueMoshiVersion = '0.4.3'
    rxJavaVersion = '2.1.4'
    rxAndroidVersion = '2.0.1'
    rxRelayVersion = '2.0.0'
    conductorVersion = '2.1.4'
}

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

这是我的应用程序级别的gradle-

apply plugin: 'com.android.application'

android {
    compileSdkVersion rootProject.ext.compileSdkVersion
    buildToolsVersion rootProject.ext.buildToolsVersion
    defaultConfig {
        applicationId "com.example.androidadvanced1"
        minSdkVersion rootProject.ext.minSdkVersion
        targetSdkVersion rootProject.ext.targetSdkVersion
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation "com.android.support:appcompat-v7:$supportLibraryVersion"
    implementation "com.android.support:design'$supportLibraryVersion"

    implementation "com.google.dagger:dagger-android:$daggerVersion"
    implementation "com.google.dagger:dagger-android-support:$daggerVersion"
    annotationProcessor "com.google.dagger:dagger-android-processor:$daggerVersion"
    annotationProcessor "com.google.dagger:dagger-compiler:$daggerVersion"

    implementation "com.squareup.retrofit2:retrofit:$retrofitVersion"
    implementation "com.squareup.retrofit2:converter-moshi:$retrofitVersion"
    implementation "com.squareup.moshi:moshi:$moshiVersion"
    annotationProcessor "com.ryanharter.auto.value:auto-value-moshi:$autoValueMoshiVersion"
    compileOnly "com.ryanharter.auto.value:auto-value-moshi-annotations:$autoValueMoshiVersion"

    compileOnly "com.google.auto.value:auto-value:$autoValueVersion"
    annotationProcessor "com.google.auto.value:auto-value:$autoValueVersion"

    implementation "io.reactivex.rxjava2:rxjava:$rxJavaVersion"
    implementation "io.reactivex.rxjava2:rxandroid:$rxAndroidVersion"
    implementation "com.jakewharton.rxrelay2:rxrelay:$rxRelayVersion"

    implementation "com.bluelinelabs:conductor:$conductorVersion"

    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'com.android.support.test:runner:1.0.2'
    androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'
}

我究竟做错了什么 ？

更新您的Gradle friend ，您的Android Studio版本，gradle和依赖项应匹配。
