：app：transformClassesWithDexForDebug花费太多时间

Question

我使用gradle 2.8运行Android Studio 1.5.1。建设过程耗费了大量时间。在Gradle控制台中，：app：transformClassesWithDexForDebug执行很长一段时间，即平均2分钟。我该怎么做才能降低gradle构建时间？ 这是我的应用程序的build.gradle：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    // buildToolsVersion "23.0.1"
    buildToolsVersion "23.0.1"


    defaultConfig {
        applicationId "com.infistart.medoboss"
        minSdkVersion 14
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

ext {
    supportLibVersion = '23.1.1'  // variable that can be referenced to keep support libs consistent
}

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