android - 多个dex文件定义lorg/apache/commons/io/IOUtils；

标签 android android-gradle-plugin dex

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，以构建一个应用程序。

但不幸的是，它并没有像我收到的这个错误那样正常工作:

Execution failed for task ':app:transformDexArchiveWithDexMergerForDebug'. com.android.build.api.transform.TransformException: com.android.dex.DexException: Multiple dex files define Lorg/apache/commons/io/IOUtils;

我的依赖关系树如下:

以下是我在项目中得到的模块:

:TOPLEVEL

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

buildscript {

        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
}

    implementation ('com.google.http-client:google-http-client-jackson2:1.22.0')

    compile "com.android.support:cardview-v7:${supportLibraryVersion}"
    compile "com.android.support:support-v4:${supportLibraryVersion}"
}

:app(根项目)

    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'

    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，我疯狂地寻找解决方案，但我发现没有任何效果。从依赖关系树中我也看不到发生了对 commons-io 的双重引用，这显然导致了这个错误。
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

很可能，我没有看到明显的东西。
非常感谢您的提前帮助!

最佳答案

问题解决了! 这是一个错误的 commons-io 依赖。 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?

只是替换

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

与

implementation 'commons-io:commons-io:1.3.2'
