java.util.zip.ZipException: duplicate entry: org/apache/http/HttpMessage.class

Question

I'm getting the following error. I have not tried to solve it the last two days, but nothing had solved the problem. Error:Execution failed for task ':app:packageAllDebugClassesForMultiDex'.

java.util.zip.ZipException: duplicate entry: org/apache/http/HttpMessage.class here is my build.gradle(app)

apply plugin: 'com.android.application'


android {
compileSdkVersion 23
buildToolsVersion '23.0.0'

defaultConfig {
    applicationId "com.mycompany.newlogin"
    minSdkVersion 15
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}

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

}
useLibrary 'org.apache.http.legacy'
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])

}

Answer 1

I too had this Error and i resolved this by removing httpcore

in your build.gradle(app) Remove these lines

compile 'org.apache.httpcomponents:httpcore:4.4.1'
compile 'org.apache.httpcomponents:httpclient:4.5'

and then add latest apache library to your build.gradle(app)

  compile group: 'org.apache.httpcomponents' , name: 'httpclient-android' , version: '4.3.5.1'

Answer 2

Have a look at your referenced packages, org.jbundle.util.osgi.wrapped.org.apache.http.client seems to contain at least some classes of httpcore, especially that one mentioned in your error message. So I guess you simply can't and shouldn't use both as dependencies, but only the ones you really need.
