找不到 signing.gradle，请将 Android build类型和>签名配置替换为您自己的配置

Question

我正在尝试构建我从github获得的Alexa Android应用程序...但它显示的是"找不到 signing.gradle，请用您自己的配置替换 Android buildType>签名配置。这是GitHub链接：-https://github.com/willblaschko/AlexaAndroid

它显示来自build.gradle文件的错误。

apply plugin: 'com.android.application'

if (file('signing.gradle').exists()) {
apply from: 'signing.gradle'
}else{
throw new TaskExecutionException(null, new Exception("Unable to find 
signing.gradle, please replace Android buildTypes > signing configs with 
your own configuration."));
}
 android {
compileSdkVersion 24
buildToolsVersion '25.0.0'
defaultConfig {
    applicationId "com.willblaschko.android.alexavoicelibrary"
    minSdkVersion 21
    targetSdkVersion 24
    versionCode 5
    versionName "2.1.1"
    multiDexEnabled true;
}

buildTypes {
    debug{
        versionNameSuffix " Debug"
        minifyEnabled false
        shrinkResources false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.releaseConfig
    }
    release {
        minifyEnabled false
        shrinkResources false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        signingConfig signingConfigs.releaseConfig
    }
}
packagingOptions {
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.2.1'

替换这些行

if (file('signing.gradle').exists()) {
    apply from: 'signing.gradle'
} else {
    throw new TaskExecutionException(null, new Exception("Unable to find signing.gradle, please replace Android buildTypes > signing configs with your own configuration."));
}

使用在实现 LWA 时生成的签名配置：

android {
    signingConfigs {
        auto_sign {
            keyAlias ''
            keyPassword ''
            storeFile file('C:/Users/UserName/.android/keystore.jks')
            storePassword ''
        }
    }
}
