程序类型已存在（android.support.compat.R $ attr）

androidIT知识

会挽雕弓如满月，西北望，射天狼。这篇文章主要讲述程序类型已存在：android.support.compat.R $ attr相关的知识，希望能为你提供帮助。
我的项目有两个模块，即app和moduleX。 app项目主要基于java构建，而moduleX完全基于Kotlin。
【程序类型已存在（android.support.compat.R $ attr）】在创建“debug”构建时，它运行正常但是当我尝试创建发布版本，即devRelease时，它会给出以下错误 -

* What went wrong: Execution failed for task ':app:transformDexArchiveWithDexMergerForDevRelease'. > com.android.build.api.transform.TransformException: java.lang.RuntimeException: java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Error while merging dex archives: Learn how to resolve the issue at https://developer.android.com/studio/build/dependencies#duplicate_classes. Program type already present: android.support.compat.R$attr

这是app level build.gradle-
apply plugin: 'com.android.application' apply plugin: 'com.facebook.testing.screenshot' apply plugin: 'kotlin-android' apply plugin: 'kotlin-kapt' apply plugin: 'kotlin-android-extensions'android { compileSdkVersion rootProject.ext.compileSdkVersion defaultConfig { applicationId "com.appname" minSdkVersion rootProject.ext.minSdkVersion targetSdkVersion rootProject.ext.targetSdkVersion versionCode 1 versionName "1.0" testInstrumentationRunner rootProject.ext.testInstrumentationRunner } flavorDimensions "environment" productFlavors { dev { dimension "environment" versionNameSuffix "-dev" applicationIdSuffix ".dev" }qa { dimension "environment" versionNameSuffix "-test" applicationIdSuffix ".test" }staging { dimension "environment" versionNameSuffix "-staging" applicationIdSuffix ".staging" }prod { dimension "environment" } }signingConfigs { Properties properties = new Properties() properties.load(project.rootProject.file('local.properties').newDataInputStream()) release { storeFile file("keystore/appname_keystore.jks") storePassword properties.getProperty('storePassword') keyAlias properties.getProperty('keyAlias') keyPassword properties.getProperty('keyPassword') } }buildTypes { debug { shrinkResources false minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' } release { shrinkResources false minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro' signingConfig signingConfigs.release } } compileOptions { sourceCompatibility = '1.8' targetCompatibility = '1.8' }bundle { language { enableSplit = false } } configurations.all { resolutionStrategy { // force certain versions of dependencies (including transitive) force 'com.squareup.okhttp3:okhttp:' + okHttpLibVersion } } }dependencies { implementation fileTree(include: ['*.jar'], dir: 'libs') //Unit testing testImplementation rootProject.ext.junit androidTestImplementation rootProject.ext.androidTestRunner androidTestImplementation rootProject.ext.espresso testImplementation rootProject.ext.mockito testImplementation rootProject.ext.facebookScreenshotTestCommon implementation rootProject.ext.facebookScreenshotTestLitho androidTestImplementation rootProject.ext.supportTestRules//Support Library & UI implementation rootProject.ext.constraintLayout implementation rootProject.ext.supportCompatV7 implementation rootProject.ext.supportDesign implementation rootProject.ext.supportCardView implementation rootProject.ext.supportCustomTabs implementation rootProject.ext.glide implementation 'com.jakewharton:butterknife:8.8.1' annotationProcessor 'com.jakewharton:butterknife-compiler:8.8.1'// Dagger dependency for DI implementation 'com.google.dagger:dagger:2.16' annotationProcessor "com.google.dagger:dagger-compiler:2.16" compileOnly 'javax.annotation:jsr250-api:1.0' implementation 'javax.inject:javax.inject:1'// RxJava lib implementation rootProject.ext.rxAndroid implementation rootProject.ext.rxJava implementation rootProject.ext.rxJavaRetrofitAdapter//Retrofit implementation(rootProject.ext.retrofit) { exclude module: 'okhttp' } implementation rootProject.ext.okHttp implementation rootProject.ext.okHttpLoggingInterceptor implementation rootProject.ext.retrofitGsonConverter implementation rootProject.ext.retrofitScalarsConverter//Memory leaks debugImplementation 'com.squareup.leakcanary:leakcanary-android:1.6.3' releaseImplementation 'com.squareup.leakcanary:leakcanary-android-no-op:1.6.3' debugImplementation 'com.squareup.leakcanary:leakcanary-support-fragment:1.6.3'//Others implementation rootProject.ext.parceler annotationProcessor rootProject.ext.parcelerAnnotationProcessor implementation rootProject.ext.lombok annotationProcessor rootProject.ext.lombokAnnotationProcessor implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlinVersion"// Fingerprint Auth implementation 'com.multidots:fingerprint-auth:1.0.1'//Module Projects api project(':energyswitchcui') }screenshots { multipleDevices true }

这是moduleX的build.gradle文件

这是项目级build.gradle文件 -
apply from: 'dependencies.gradle'buildscript { ext.kotlinVersion = '1.3.30' repositories { google() jcenter() } dependencies { classpath 'com.android.tools.build:gradle:3.3.2' classpath 'com.facebook.testing.screenshot:plugin:0.8.0' classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion" // NOTE: Do not place your application dependencies here; they belong // in the individual module build.gradle files } }allprojects { repositories { google() jcenter() } }task clean(type: Delete) { delete rootProject.buildDir }

这是依赖.gradle-
ext { //Android minSdkVersion = 24 targetSdkVersion = 28 compileSdkVersion = targetSdkVersion testInstrumentationRunner = "com.appname.runner.SnapshotTestRunner" androidSupportLibVersion = "28.0.0" okHttpLibVersion = "3.14.0"//Unit testing junit = "junit:junit:4.12" androidTestRunner = "com.android.support.test:runner:1.0.2" espresso = "com.android.support.test.espresso:espresso-core:3.0.2" mockito = "org.mockito:mockito-all:1.10.19" facebookScreenshotTestCommon = "com.facebook.testing.screenshot:layout-hierarchy-common:0.8.0" facebookScreenshotTestLitho = "com.facebook.testing.screenshot:layout-hierarchy-litho:0.8.0" supportTestRules = "com.android.support.test:rules:1.0.2"//Support Library & UI constraintLayout = "com.android.support.constraint:constraint-layout:1.1.3" supportCompatV7 = "com.android.support:appcompat-v7:$androidSupportLibVersion" supportDesign = "com.android.support:design:$androidSupportLibVersion" supportCardView = "com.android.support:cardview-v7:$androidSupportLibVersion" supportCustomTabs = "com.android.support:customtabs:$androidSupportLibVersion" glide = "com.github.bumptech.glide:glide:3.7.0"// RxJava lib rxAndroid = "io.reactivex.rxjava2:rxandroid:2.0.1" rxJava = "io.reactivex.rxjava2:rxjava:2.1.8" rxJavaRetrofitAdapter = "com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0"//Retrofit retrofit = "com.squareup.retrofit2:retrofit:2.4.0" okHttp = "com.squareup.okhttp3:okhttp:$okHttpLibVersion" okHttpLoggingInterceptor = "com.squareup.okhttp3:logging-interceptor:$okHttpLibVersion" retrofitGsonConverter = "com.squareup.retrofit2:converter-gson:2.3.0" retrofitScalarsConverter = "com.squareup.retrofit2:converter-scalars:2.3.0"//Others parceler = "org.parceler:parceler-api:1.1.6" parcelerAnnotationProcessor = "org.parceler:parceler:1.1.6" lombok = "org.projectlombok:lombok:1.16.16" lombokAnnotationProcessor = "org.projectlombok:lombok:1.16.16" }

我已经尝试了许多答案，即Error : Program type already present: android.support.design.widget.CoordinatorLayout$Behavior
但这里没有任何工作。
答案嗨，我已经提出了解决方案，只需很少的版本更改就可以在gradles下面成功运行：
