错误：任务＆＃39;：app：transformDexArchiveWithExternalLibsDexMergerForDebug＆＃39;执行失败。 java.lang.RuntimeException：com.android.builder.dexing.DexArchiveMergerException：无法合并dex

我使用的是Android Studio 3.0.1版。

我也尝试过清理项目＆＃39;和＆＃39;重建项目＆＃39;。

* project build gradle

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.3'

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

* module build gradle

apply plugin: 'com.android.application'
apply plugin: 'com.google.protobuf'
ext {
    grpcVersion = '1.4.0'
}

    }
}

当我进行重建项目时，我收到如下错误。

错误：任务＆＃39;：app：transformClassesWithMultidexlistForDebug＆＃39;执行失败。 java.io.IOException：不能写[C：\ Users \ backkom \ AndroidStudioProjects \ SpeechTest \ app \ build \ intermediates \ multi-dex \ debug \ componentClasses.jar]（不能读[C： \用户\ backkom.gradle \缓存\模块-2 \文件-2.1 \ com.google.protobuf \的protobuf-java的\ 3.3.1 \ e8964a2667e55d11a4505b329a4c34247663920b \的protobuf-java的3.3.1.jar（;;;;;; * * .class）]（重复的zip条目[protobuf-java-3.3.1.jar：com / google / protobuf / ExperimentalApi.class]））

Answer 1

从您的错误日志中，似乎您的目录 backkom 不适用于android studio。所以请检查你的目录

 C:\Users\backkom

是否可写。通过这样做。转到该目录并检查其权限。它是否已经读取和写入权限。

Answer 2

根据我的理解，

试试这个：

Clean Project button.
Rebuild Project button from the Build menu.

使用此

更改local.properties

org.gradle.jvmargs=-XX\:MaxHeapSize\=512m -Xmx512m

以这种方式定义gradle

android {
compileSdkVersion 26
buildToolsVersion '26.0.2'
defaultConfig {
applicationId "com.xxxx.xxxx"
minSdkVersion 21
targetSdkVersion 26
versionCode 7
versionName "0.7"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
multiDexEnabled true
}

 buildTypes {
release {
    minifyEnabled true
    shrinkResources true
    proguardFiles getDefaultProguardFile('proguard-android.txt'),   'proguard-rules.pro'
}

}

在项目中添加此multidex

compile 'com.android.support:multidex:1.0.1'

并在Manifest中定义它

Android应用构建错误。无法合并dex
