我也是參考上面的配置的.我的配置如下,要配置的地方有兩處:

1> Project 的 build.gradle :

// 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:1.5.0'

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

        //配置Android annotations
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

    }
}

allprojects {
    repositories {
        jcenter()
    }
}

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

關鍵是： classpath ‘com.neenbedankt.gradle.plugins:android-apt:1.4+’

2> Module的 build.gradle :

apply plugin: 'com.android.application'

//配置Android annotations
apply plugin: 'android-apt'
def AAVersion = '3.3.2'

android {
    compileSdkVersion 22
    buildToolsVersion "23.0.2"
 


    defaultConfig {
        applicationId "com.huaisheng.mayi"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

//配置Android annotations
apt {
    arguments {
        androidManifestFile variant.outputs[0]?.processResources?.manifestFile
        // if you have multiple outputs (when using splits), you may want to have other index than 0

        // you should set your package name here if you are using different application IDs
        // resourcePackageName "your.package.name"

        // You can set optional annotation processing options here, like these commented options:
        // logLevel 'INFO'
        // logFile '/var/log/aa.log'
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:22.2.1'
    //配置Android annotations
    apt "org.androidannotations:androidannotations:$AAVersion"
    compile "org.androidannotations:androidannotations-api:$AAVersion"
}

重新編譯一下,即可!
