Question

我遇到了一个非常愚蠢的问题。我无法组装我的项目。

我创建了单个项目，例如数据库管理，api，自定义布局等。现在我正在尝试将所有这些项目合并为一个，以构建单个应用程序。

但不幸的是，它没有像我收到这个错误那样有效：

任务执行失败＆＃39;：app：transformDexArchiveWithDexMergerForDebug＆＃39;。 com.android.build.api.transform.TransformException：com.android.dex.DexException：多个dex文件定义Lorg / apache / commons / io / IOUtils;

我的依赖树如下：

以下是我在项目中获得的模块：

：TOPLEVEL 的

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta5'
        classpath "io.realm:realm-gradle-plugin:3.7.2"

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

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
        maven { url "https://jitpack.io" }
        maven { url 'https://maven.google.com' }
        maven { url 'https://oss.jfrog.org/libs-snapshot' }
    }

    project.ext {
        minSdk=14
        targetSdk=26
        buildVersion="26.0.1"
        compileSdk=26
        supportLibraryVersion="26.0.2"
        set('supportLibraryVersion',supportLibraryVersion)
    }
}

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

：API 的

dependencies {
    implementation 'org.jsoup:jsoup:1.10.3'
    implementation ('com.google.http-client:google-http-client-jackson2:1.22.0')
    api 'com.google.code.gson:gson:2.8.1'
    api ('com.google.apis:google-api-services-youtube:v3-rev44-1.14.1-beta')
    api 'io.reactivex.rxjava2:rxandroid:2.0.1'
    api 'io.reactivex.rxjava2:rxjava:2.1.3'
}

：DatabaseManagment 的

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    implementation "com.android.support:appcompat-v7:${supportLibraryVersion}"
    implementation project(':api')
    implementation 'org.apache.commons:commons-io:1.3.2'
}

：onboarder 的

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile "com.android.support:appcompat-v7:${supportLibraryVersion}"
    compile "com.android.support:cardview-v7:${supportLibraryVersion}"
    compile "com.android.support:support-v4:${supportLibraryVersion}"
}

：app（根项目）

dependencies {
    implementation fileTree(include: ['*.jar'], dir: 'libs')
    /** Android/Google Support Libraries **/
    implementation "com.android.support:appcompat-v7:${supportLibraryVersion}"
    implementation 'com.android.support:multidex:1.0.2'
    /** UI dependencies **/
    implementation 'com.github.jetradarmobile:multibackstack:1.2.1'
    //has dependencies on old appcompat version
    implementation 'com.ashokvarma.android:bottom-navigation-bar:2.0.2'
    //has dependencies on old appcompat version
    implementation 'com.github.bumptech.glide:glide:4.0.0'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.0.0'
    implementation 'com.android.support.constraint:constraint-layout:1.1.0-beta1'
    implementation 'com.wdullaer:swipeactionadapter:2.0.0'
    implementation project(':onboarder')
    /** Techniqual implementations */
    implementation project(':DatabaseManagement')
    implementation project(':api')
}

尝试过的解决方案：
在过去的3个小时里，我疯狂地找到了一个解决方案，但我找不到任何工作。我不能从依赖树中看到对commons-io的双重引用正在发生，这会引起这个错误。
Multidex不是这里的问题，没有multidex它也无法组装。

我正在使用Android Studio 3 Beta 5

可能，我错过了看到明显的我非常感谢你的帮助！

Answer 1

问题解决了！这是一个错误的公共 - 依赖性。可以在此处找到此失败的原因：What is the difference between maven dependencies org.apache.commons:commons-io and commons-io:commons-io?

只需替换

实施'org.apache.commons：commons-io：1.3.2'

带

实施'commons-io：commons-io：1.3.2'

多个dex文件定义Lorg / apache / commons / io / IOUtils;
