将字节码转换为 dex 时出错：原因：com.android.dex.DexException：

Question

我正在开发一个 android 应用程序并且 gradle 构建工作正常但是现在当我构建我的 android 项目时，gradle 构建失败并显示以下错误

Error converting bytecode to dex: Cause: com.android.dex.DexException: Multiple dex files define Landroid/arch/core/internal/SafeIterableMap$Entry; Message{kind=ERROR, text=Error converting bytecode to dex: Cause: com.android.dex.DexException: Multiple dex files define Landroid/arch/core/internal/SafeIterableMap$Entry;, sources=[Unknown source file], original message=UNEXPECTED TOP-LEVEL EXCEPTION: com.android.dex.DexException: Multiple dex files define Landroid/arch/core/internal/SafeIterableMap$Entry; , tool name=Optional.of(Dex)}

注：我已经在我的 build.gradle(app) 中添加了 multiDexEnabled true 并且我还清理并重建了项目

我正在使用 Android studio 3.1

我的 build.gradle(app) 低于

apply plugin: 'com.android.application'

android {
compileSdkVersion 26
defaultConfig {
    multiDexEnabled true
    applicationId "atnd.mdadil2019.myprojectname"
    minSdkVersion 15
    targetSdkVersion 26
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

}

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

}


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

我的build.gradle（项目）如下

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.0.1'


    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    classpath 'com.google.gms:google-services:3.2.1'
   }
}

allprojects {
repositories {
    google()
    jcenter()
    mavenCentral()
    maven {
        url "http://dl.bintray.com/jlmd/maven"
    }
    maven { url 'https://maven.google.com' }
}
}

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

Answer 1

你的错误是你有 2+ 个声明 android.arch.core.internal.SafeIterableMap$Entry.

的依赖项

首先，将您的 Room 依赖项从 1.0.0-alpha1 升级到 1.0.0。 Room 已经有几个月没有 alpha 了。

如果这不能解决您的问题，您将需要运行一份 Gradle 依赖报告并找到您从哪里获得 2+ 个版本的 android.arch 库，然后制作确保您获得了这些库的最新版本。
