build：gradle：3.2.1：无法获取未知属性'processResourcesTask'

Question

Android Studio 3.2.1

在项目build.gradle中：

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

buildscript {
    ext.kotlin_version = '1.2.50'
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"


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

allprojects {
    repositories {
        google()
        jcenter()
    }
}

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

在app / build.gradle中：

apply plugin: 'com.android.application'
apply plugin: 'kotlin-kapt'
apply plugin: 'kotlin-android'

kapt {
    arguments {
        arg("resourcePackageName", android.defaultConfig.applicationId)
        arg("androidManifestFile", variant.outputs[0]?.processResourcesTask?.manifestFile)
    }
}

但是我得到了错误：

Could not get unknown property 'processResourcesTask' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=debug, filters=[], versionCode=421, versionName=2.1.421}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.

在build:gradle:3.2.1之前一切正常。
