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

It occurs this error.

The app builds success but when I get build apk, android studio show this message

This is my gradle

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '25'
    defaultConfig {
        applicationId "com.example.thewell_dev.fourscompany"
        minSdkVersion 19
        targetSdkVersion 24

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

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'

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

}

I think external libraries have Commons-io-1.3.2.jar Commons-io-2.4.jar and both have CopyUtils.class

Anyway, It can't build apk and show that message.

Please anyone help me please

回答1:

There is more than one dependency you have integrated which uses Apache Commons. just exclude them using following code in gradle.

compile('YOUR_DEPENDENCY') {
    exclude module: 'commons-io'
}

回答2:

Found the solution for this issue . You need to exclude common-io from your app build.gradle .

android {
    configurations{
        all*.exclude module: 'commons-io'
    }
}

回答3:

Techierj answer is correct, but it will also exclude commons-io:2.4, and in my case I needed that. So you can exclude by specific group:

compile('YOUR_DEPENDENCY') {
    exclude group: 'org.apache.commons', module: 'commons-io'
}

This will only exclude version 1.3.2 from org.apache.commons, and will mantain commons.io:commons.io:2.4
