android - Android Studio 无法识别默认配置

Question

在更新到 Android studio 3.1 时，出现此错误

Android Gradle 插件无法识别 SourceSet“defaultConfig”。也许你拼错了什么？

构建渐变

apply plugin: 'com.android.application'

buildscript {
    repositories {
        mavenCentral()
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0'
        classpath 'com.google.gms:google-services:3.1.1'
        // classpath 'com.android.tools.build:gradle:2.3.3'
        //classpath 'com.android.tools.build:gradle:2.2.2'
    }
}
allprojects {
    repositories {
        mavenLocal()
        mavenCentral()
        jcenter()

    maven {
        url 'https://maven.google.com/'
        name 'Google'
    }
}
}


apply plugin: 'android'

dependencies {
    implementation fileTree(dir: 'libs', include: '*.jar')
    implementation 'com.google.android.gms:play-services-auth:12.0.1'
    implementation 'org.apache.commons:commons-lang3:3.4'
    implementation 'com.github.barteksc:android-pdf-viewer:2.7.0'
    implementation 'com.google.firebase:firebase-messaging:12.0.1'
    implementation 'com.google.android.gms:play-services-gcm:12.0.1'

}

android {
    compileSdkVersion 27
    buildToolsVersion '27.0.3'
    //buildToolsVersion "21.1.2"

    dexOptions {
        preDexLibraries = false

    compileOptions {

        targetCompatibility JavaVersion.VERSION_1_8
    }
sourceSets {
    main {
        manifest.srcFile 'AndroidManifest.xml'
        java.srcDirs = ['src']
        resources.srcDirs = ['src']
        aidl.srcDirs = ['src']
        renderscript.srcDirs = ['src']
        res.srcDirs = ['res']
        assets.srcDirs = ['assets']
    }

    defaultConfig {
        applicationId "com.mpathway.xxxx"
        minSdkVersion 14
        targetSdkVersion 27
        versionCode 2
        versionName "2.0"
    }
    // Move the tests to tests/java, tests/res, etc...
//        instrumentTest.setRoot('tests')

    // Move the build types to build-types/<type>
    // For instance, build-types/debug/java, build-types/debug/AndroidManifest.xml, ...
    // This moves them out of them default location under src/<type>/... which would
    // conflict with src/ being used by the main source set.
    // Adding new build types or product flavors should be accompanied
    // by a similar customization.
    debug.setRoot('build-types/debug')
    release.setRoot('build-types/release')
}
defaultConfig {
    testInstrumentationRunner 'android.support.test.runner.AndroidJUnitRunner'
}
}

apply plugin: 'com.google.gms.google-services'

我在编译时收到警告，即使我删除了 defaultconfig 并出错

有人可以帮我解决这个问题吗？让我知道用什么代替它谢谢

您有多个 defaultConfig 闭包。理想情况下，只有一个。

无论如何，defaultConfig 直接进入 android 闭包内部，而不是 sourceSets 闭包内部。
