Android studio 更新构建错误

Question

I have updated the android studio to latest version : android studio 2.2 preview 1

it supports JDK 1.8(java 8)

after updating the studio getting following build error

Cause: com.android.build.gradle.AppPlugin cannot be cast to groovy.lang.GroovyObject

Error:Cause: com.android.build.gradle.AppPlugin cannot be cast to groovy.lang.GroovyObject

此意外错误的可能原因包括:

• Gradle 的依赖项缓存可能已损坏(这有时会在网络连接超时后发生。) 重新下载依赖项并同步项目(需要网络)
• Gradle 构建过程(守护进程)的状态可能已损坏。停止所有 Gradle 守护进程可能会解决此问题。 停止 Gradle 构建过程(需要重新启动)
• 您的项目可能正在使用第三方插件，该插件与项目中的其他插件或项目请求的 Gradle 版本不兼容。

如果 Gradle 进程损坏，您还可以尝试关闭 IDE，然后杀死所有 Java 进程。

请帮忙解决这个问题

Will be adding my build.gradle file

buildscript {

repositories {
    maven { url 'https://maven.fabric.io/public' }
    flatDir { dirs '/usr/local/DexGuard-7.0.22/lib' }
    mavenCentral()                  // For the Android plugin.
}

dependencies {
    classpath 'io.fabric.tools:gradle:1.+'
    classpath ':dexguard:'
}}`apply plugin: 'com.android.application'


apply plugin: 'dexguard'
apply plugin: 'io.fabric'

afterEvaluate { project ->
  tasks['dexguardRelease'].enabled = true
 }repositories {
     maven { url 'https://maven.fabric.io/public' }
}android {
compileSdkVersion 23
buildToolsVersion "23.0.3"

    targetSdkVersion 23

    versionName "1.0.1"
    useLibrary 'org.apache.http.legacy'
}

buildTypes {

        //proguardFile 'proguard-project.txt'
    }
    release {

        proguardFile getDefaultDexGuardFile('dexguard-release.pro')
        proguardFile 'dexguard-project.txt'

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

Top level gradle

buildscript {
repositories {
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:2.2.0-alpha1'
    classpath 'com.google.gms:google-services:3.0.0'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}}allprojects {
repositories {
    jcenter()
}}task clean(type: Delete) {
delete rootProject.buildDir}

我的一个项目也遇到了同样的问题。我将 gradle 版本降回次要版本，它为我解决了这个问题。

classpath 'com.android.tools.build:gradle:2.1.0'
