Unable to exclude duplicate libraries in Gradle

I'm trying to connect library to my project in Gradle:

compile 'com.balancedpayments:balancedpayments:1.4'

When I click "Sync Now" project building without errors, but when I run my project IDE shows errors:

I found the description of the problem - it is a conflict of libraries. To solve this problem are advised to eliminate conflicting library. To do this, I do so:

configurations {
    all*.exclude module: 'httpclient'
    all*.exclude module: 'commons-logging'
}

Warnings disappear, but the error remains. Can you please tell how to eliminate these libraries.

Thanks.

I had a similar problem when I use HttpClient in api 23. I import org.apache.http.legacy.jar the problem appear. I use useLibrary 'org.apache.http.legacy' solve it.

"com.android.dex.DexException: Multiple dex files define "

This vexing error is caused when two or more copies of a .class file or jarfile's contents have been inadvertently included into a project. (Newbies to Gradle and/or Android Studio get blocked by this one often enough).

  1. Try excluding it in your app's top-level build.gradle-

    android {
    ...
    packagingOptions {
        exclude('org/apache/commons/codec/*')
    }
}

  2. Check if the library was included as dependency more than once: review all of your project's build.gradle files to ensure it's been included only once.

     compile 'org.apache.commons.code' ...

  3. A library or subproject may also includes a copy of the duplicated library or classfile: you can exclude it where the library is compiled into your app, look for its compile spec in your build.gradle file(s)-

    dependencies {
    ...
    compile('com.googlecode.json-simple:json-simple:1.1.1') {
        exclude group: 'org.hamcrest'
    }
}

  4. If that doesn't work, try appending ", module: 'library'" to the exclude line, i.e.-

        compile('com.googlecode.json-simple:json-simple:1.1.1') {
        exclude group: 'org.hamcrest', module: 'library'
    }

  5. To determine exactly which library or subproject is including the duplicated classfiles, try running gradle with --debug and reviewing the console output in order to trace where that inclusion originated-

    % gradle --debug release 2>&1 | less
