Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'. > com.android.build.api.transform.TransformException

Question

我是 android 的新人。我正在尝试在我的应用程序中添加 Google 登录功能，但是当我在我的 build.gradle 文件中添加 com.google.android.gms:play-services-auth:17.0.0 时，

我遇到了这个错误：

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: androidx/versionedparcelable/CustomVersionedParcelable.class

请提出解决方案，我花了一整天但无法解决。

Build.gradle 代码是：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    buildToolsVersion "29.0.1"
    defaultConfig {
        multiDexEnabled true
        applicationId "com.example.mawai.smartlearn"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
     compile 'com.android.support:multidex:1.0.0'

    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    // compile 'com.android.support:appcompat-v7:26.+'
     compile 'com.android.support:appcompat-v7:28.0.0'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    testCompile 'junit:junit:4.12'

     compile 'com.google.android.gms:play-services-auth:17.0.0'
}

17.0.0及以上版本需要使用AndroidX，所以有2个选项:

1) Downgrade com.google.android.gms:play-services-auth to older version

2) Add/Migrate AndroidX to your app (Recommended)
