Issue in including a library in my android application

Question

I am perfectly aware that similar questions exist in the site, but none of them solved my issue. The word is, I am trying to use "openimaj" library into my android application, in android studio. everything works fine before importing the dependency

'org.openimaj:core-audio:1.3.1'

But when I import this dependency the following error appears!

Error:Execution failed for task ':app:transformClassesWithDexForDebug'.
> com.android.build.api.transform.TransformException:
com.android.ide.common.process.ProcessException:
org.gradle.process.internal.ExecException: 
Process 'command 'C:\ProgramFiles\Java\jdk1.8.0_66\bin\java.exe'' 
finished with non-zero exit value 2

Please notice that I utilized the tutorial from http://www.openimaj.org/UseLibrary.html. It is based on Maven build configuration, but I convert it into gradle form. here is my app level gradle.build:

apply plugin: 'com.android.application'
apply plugin: 'maven'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.shadan.voicerecognitionmodule"
        minSdkVersion 19
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    testCompile 'junit:junit:4.12'
    compile ('com.android.support:appcompat-v7:23.1.1')
    compile ('com.android.support:design:23.1.1')
    compile ('org.openimaj:core-audio:1.3.1')  //I TRY TO IMPORT THIS
}

and my project level build.gradle is:

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

 buildscript {
     repositories {
         jcenter()
     }
     dependencies {
         classpath 'com.android.tools.build:gradle:1.5.0'

         // NOTE: Do not place your application dependencies here; they belong
         // in the individual module build.gradle files
     }
 }

 allprojects {
     repositories {
         jcenter()
         maven { url "http://snapshots.openimaj.org" }
         maven { url "http://maven.openimaj.org" }
     }
 }

 task clean(type: Delete) {
     delete rootProject.buildDir
 }

EDIT:

my gradle console error is:

 UNEXPECTED TOP-LEVEL EXCEPTION:
