我在安装
android studio的最新预览版后再次尝试构建我的项目,但是在更新gradle版本时会出现以下异常：

我的项目的Gradle文件如下：
的build.gradle(项目)：
buildscript {
repositories {
jcenter()
google()
}
dependencies {
classpath 'com.android.tools.build:gradle:3.2.0-alpha18'
}}allprojects {
repositories {
jcenter()
}}
的build.gradle(APP)：
apply plugin: 'com.android.application'
android {
compileSdkVersion 27
buildToolsversion ’27 .0.3′
defaultConfig { applicationId "com.visionapps.app.swipe" minSdkVersion 21 targetSdkVersion 27 } buildTypes { release { minifyEnabled false proguardFiles getDefaultProguardFile('proguard-android.txt'),'proguard-rules.txt' } } packagingOptions { exclude 'meta-inf/license.txt' exclude 'meta-inf/LICENSE' }}dependencies { implementation filetree(include: ['*.jar'],dir: 'libs') androidTestImplementation('com.android.support.test.espresso:espresso-core:2.2.2',{ exclude group: 'com.android.support',module: 'support-annotations' }) implementation 'com.android.support:appcompat-v7:27.1.1' implementation 'com.android.support:support-v4:27.1.1' implementation 'com.android.support:design:27.1.1' implementation 'com.android.support.constraint:constraint-layout:1.1.0' implementation files('libs/otto-1.3.3.jar') testImplementation 'junit:junit:4.12' implementation 'com.android.support:cardview-v7:27.1.1' implementation 'com.android.support:customtabs:27.1.1' implementation 'com.android.support:animated-vector-drawable:27.1.1'}
解决方法
去设置/ Gradle / Android Studio. 然后选中“启用嵌入式Maven存储库”. 你很高兴去.
