IntelliJ仍然要求Jack for Java 8

Question

我是Android的新手。 我正在使用 build：gradle：2.3.3 。并设置IntelliJ 2017.2 Eap mannualy使用 Gradle 4.0 但我有一个错误：

   Error:Jack is required to support java 8 language features. Either enable Jack or remove sourceCompatibility JavaVersion.VERSION_1_8.

我的朋友， 顶层：

// 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:2.3.3'
        classpath 'org.codehaus.groovy:gradle-groovy-android-plugin:0.3.10'

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

allprojects {
    repositories {
        jcenter()
    }
}

app gradle：

apply plugin: 'com.android.application'

//apply plugin: 'android-aspectj'

android {
    compileSdkVersion 26
    buildToolsVersion "26.0.0"
    defaultConfig {
        applicationId "com.headfirst.irina.stopwatch"
        minSdkVersion 15
        targetSdkVersion 26
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_8
        targetCompatibility JavaVersion.VERSION_1_8
    }
}



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

    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:26.+'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'
    compile 'com.android.support:support-v4:26.+'
    testCompile 'junit:junit:4.12'
}

Intellij gradle设置：

我需要Android的AspectJ支持，所以我不能使用jack。

如何使用jack来修复此错误？
