android gradle合并,android – 无法合并dex gradle 3.0.1

我是Android编程和StackOverflow的新手.我查看了规则并已经搜索了互联网和其他StackOverflow帖子,但似乎没有什么能解决我的问题.

我想做什么

我正在从网站上抓新闻文章,我想要使用这些库：

> JSoup

> RetroFit

> GSON

问题

当我尝试将应用程序安装到我的Android设备时,它失败并出现以下错误：

Error:Execution failed for task ‘:app:transformDexArchiveWithExternalLibsDexMergerForDebug’.

java.lang.RuntimeException: com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex

我从互联网和其他StackOverflow帖子尝试了什么

>尝试添加multiDexEnabled trueto我的应用程序级gradle文件

>添加了这个库实现’com.android.support:multidex:1.0.3′

>将此添加到我的清单文件android：name =“android.support.multidex.MultiDexApplication”

>尝试将所有库更新到最新版本.

>尝试清理和重建项目

>尝试清理,使缓存无效并重新启动

>注释掉GSON导入并尝试使用从其他模块导入的GSON

>为所有人强制推出GSON版本

这是gradle信息日志输出：

最后这是我的app gradle文件：

apply plugin: 'com.android.application'

android {

defaultConfig {

minSdkVersion 15

targetSdkVersion 27

versionCode 1

versionName "1.0"

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

vectorDrawables.useSupportLibrary= true

multiDexEnabled true

}

buildTypes {

release {

minifyEnabled false

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

}

}

configurations.all {

resolutionStrategy.force 'com.google.code.findbugs:jsr305:2.0.1'

}

}

dependencies {

// JSON Parsing

implementation 'com.squareup.retrofit2:converter-gson:2.3.0'

}

我正在使用Gradle 3.0.1

如果有人可以帮助我会非常感激！我一直在摸不着头脑.

谢谢大家

更新1

当我注释掉GSON导入时,我得到这个错误：

What went wrong:

Execution failed for task ‘:app:transformClassesWithMultidexlistForDebug’.

java.io.IOException: Can’t write [/Users/kim/Documents/Android-Studio-Projects/app/build/intermediates/multi-dex/debug/componentClasses.jar] (Can’t read [/Users/kim/.gradle/caches/modules-2/files-2.1/com.google.code.gson/gson/2.7/751f548c85fa49f330cecbb1875893f971b33c4e/gson-2.7.jar(;;;;;;**.class)] (Duplicate zip entry [gson-2.7.jar:com/google/gson/annotations/Expose.class]))

我强迫gradle使用一个版本的gson但得到错误：
