错误：任务＆＃39;：app：transformClassesWithDexForDebug＆＃39;执行失败使用Google Pubsub客户端库时

Question

当我尝试运行应用程序时出现以下错误：

  

错误：任务＆＃39;：app：transformClassesWithDexForDebug＆＃39;执行失败。    com.android.build.api.transform.TransformException：java.lang.RuntimeException：java.lang.RuntimeException：com.android.ide.common.process.ProcessException：java.util.concurrent.ExecutionException：java.lang.UnsupportedOperationException < / p>

这是Build.gradle文件：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 24
    buildToolsVersion "24.0.1"
    defaultConfig {
        applicationId "com.manzoor.myapplication"

        targetSdkVersion 24
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }
    buildTypes {
        debug {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    dexOptions {
        incremental true
        javaMaxHeapSize "4g"
        preDexLibraries = false
    }
    android.packagingOptions {

        exclude 'com.google.protobuf.AbstractMessageLite'

    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])

    compile group: 'com.google.cloud', name: 'google-cloud-pubsub', version: '0.4.0'
    compile 'com.android.support:appcompat-v7:24.2.1'
