AndroidStudio用gradle编译中文乱码

在Gradle Scripts下的 

build.gradle(Module:app)文件中，增加一行代码： 

android { compileOptions.encoding = "GBK" }  

该文件全文如下：

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 22 
    buildToolsVersion "22.0.1" 

    android { compileOptions.encoding = "GBK" } 

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

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    compile 'com.android.support:appcompat-v7:22.1.1' 
}
