android-studio - 错误:任务':app:transformClassesWithJarMergingForDebug CopyUtil.class的执行失败

Question

我在android studio中制作了一个项目，但突然发生了错误

我今天没有在build.gradle中添加gradle，并且在我构建项目的早晨没有问题

Error:Execution failed for task ':app:transformClassesWithJarMergingForDebug'.
> com.android.build.api.transform.TransformException: java.util.zip.ZipException: duplicate entry: org/apache/commons/io/CopyUtils.class

这是我的build.gradle

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })

    testCompile 'junit:junit:4.12'

    compile 'com.mindorks:placeholderview:0.6.1'
    compile 'com.thoughtbot:expandablerecyclerview:1.3'

    compile 'com.android.support:multidex:1.0.0'
}

我对此一无所知

请您帮我解决这个问题？

Answer 1

我有完全相同的问题，我怀疑新的Android Studio / Gradle版本有问题，因为该问题是在将Android Studio从2.2.3升级到2.3之后出现的
我用gradlew app:dependencies检查了依赖关系树，但是commons-io似乎没有重复。 (见下文)
当我在android studio中使用Ctrl + N搜索CopyUtils类时，我实际上得到了2个类:
Ctrl+N search CopyUtils
编辑
我用find命令调查了缓存文件夹，并在不同的文件夹中得到了2个commons-io jar:

./.gradle/caches/modules-2/files-2.1/commons-io/commons-io/1.3.2/b6dde38349ba9bb5e6ea6320531eae969985dae5/commons-io-1.3.2.jar

和

./.gradle/caches/modules-2/files-2.1/org.apache.commons/commons-io/1.3.2/b6dde38349ba9bb5e6ea6320531eae969985dae5/commons-io-1.3.2.jar

编辑2
commons-io似乎会包含自身，从而导致重复类(???)
从依赖关系树中可以看出:

+--- org.apache.commons:commons-io:1.3.2
|    \--- commons-io:commons-io:1.3.2

我真的不知道为什么，这个问题以前没有出现过。
尽管如此，修改依赖关系仍然可以解决我的问题:

compile('org.apache.commons:commons-io:1.3.2'){
    exclude module: 'commons-io'
}
