Android Paypal依赖项非预期的最高级别异常：任务dexDebug的执行失败

我正在开发一个Android应用程序，并希望集成Paypal。编译时出现以下错误：

我的构建gradle依赖项：

    apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.0'

    defaultConfig {
        applicationId "com.pickandpark.pickandpark"
        minSdkVersion 17
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
}

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 'com.google.android.gms:play-services:8.3.0'
    compile 'com.facebook.android:facebook-android-sdk:4.0.0'
    compile 'com.google.android.gms:play-services-ads:8.3.0'
    compile 'com.google.android.gms:play-services-identity:8.1.0'
    compile 'com.google.android.gms:play-services-gcm:8.1.0'
    compile 'org.jbundle.util.osgi.wrapped:org.jbundle.util.osgi.wrapped.org.apache.http.client:4.1.2'
    compile 'com.android.support:support-v4:23.1.1'
    compile 'com.google.code.gson:gson:2.5'
    compile 'com.paypal.sdk:paypal-android-sdk:2.12.4'
}

因此，我绝对知道这与Paypal依赖关系有关。我认为我必须从Paypal中排除某些依赖关系，我已经尝试将Gson从Paypal中排除，但这不能解决问题。

提前致谢！
