Question

我刚刚将Android Studio更新到了3.5版。运行App时发生错误。

org.gradle.api.tasks.TaskExecutionException：任务执行失败   '：app：checkDebugDuplicateClasses'。

原因1：java.util.concurrent.ExecutionException：   java.lang.RuntimeException：重复的类   android.support.v4.accessibilityservice.AccessibilityServiceInfoCompat   在模块classes.jar中找到   （com.android.support:support-compat:28.0.0）和classes.jar   （com.android.support:support-v4:23.3.0）重复的类   在模块中找到android.support.v4.app.ActionBarDrawerToggle   classes.jar（com.android.support:support-core-ui:28.0.0）和   classes.jar（com.android.support:support-v4:23.3.0）重复的类   在模块中找到android.support.v4.app.ActionBarDrawerToggle $ Delegate   classes.jar（com.android.support:support-core-ui:28.0.0）和   classes.jar（com.android.support:support-v4:23.3.0）重复的类   在中找到了android.support.v4.app.ActionBarDrawerToggle $ DelegateProvider   模块classes.jar（com.android.support:support-core-ui:28.0.0）和   classes.jar（com.android.support:support-v4:23.3.0）重复的类   的android.support.v4.app.ActionBarDrawerToggle $ SlideDrawable   模块classes.jar（com.android.support:support-core-ui:28.0.0）和   classes.jar（com.android.support:support-v4:23.3.0）重复的类   在classes.jar模块中找到android.support.v4.app.ActivityCompat   （com.android.support:support-compat:28.0.0）和classes.jar   （com.android.support:support-v4:23.3.0）重复的类   在classes.jar模块中找到android.support.v4.app.ActivityCompat $ 1   （com.android.support:support-compat:28.0.0）和classes.jar   （com.android.support:support-v4:23.3.0）重复的类   android.support.v4.app.ActivityCompat $ OnRequestPermissionsResultCallback   在模块classes.jar中找到   （com.android.support:support-compat:28.0.0）和classes.jar   （com.android.support:support-v4:23.3.0）重复的类   android.support.v4.app.ActivityCompat $ SharedElementCallback21Impl   在模块classes.jar中找到   （com.android.support:support-compat:28.0.0）和classes.jar   （com.android.support:support-v4:23.3.0）

apply plugin: 'com.android.application'

android {
    compileSdkVersion 28
    defaultConfig {
        applicationId "com.example.alquickstop"
        minSdkVersion 15
        targetSdkVersion 28

gradle（应用程序）：

buildscript {

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'

        jcenter()
        mavenCentral()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
        maven { url "https://jitpack.io" }

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

Answer 1

重复的班级 android.support.v4.accessibilityservice.AccessibilityServiceInfoCompat 在模块classes.jar中找到（com.android.support:support-compat:28.0.0）和classes.jar （com.android.support:support-v4:23.3.0）重复的类

您应该添加

configurations {
    all*.exclude group: 'com.android.support', module: 'support-v4'
}

Answer 2

转到gradle.properties并编写以下两行代码：

android.useAndroidX=true
android.enableJetifier=true

然后清理和重建项目，然后运行。

org.gradle.api.tasks.TaskExecutionException：任务'：app：checkDebugDuplicateClasses'的执行失败
