尝试在 android studio 中生成签名的 apk 会出错

Question

我想在我的项目的 android studio 中生成签名的 apk，但它给了我错误。我是 android 新手，请帮助我。

Gradle 控制台提供如下堆栈跟踪：

Executing tasks: [:app:assembleRelease]

我的 Gradle 文件是这样的：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 21
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.example.mubashirgul.androidtest"
        minSdkVersion 15
        targetSdkVersion 21
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

            debug {

            }

    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:appcompat-v7:22.0.0'
}

这就是我的做法：

build.gradle：

apply plugin: 'com.android.application'

android {
.
.
.

signingConfigs {
    release
}

buildTypes {
    release {
        minifyEnabled true
        proguardFiles 'proguard.pro'
        debuggable false
        signingConfig signingConfigs.release
    }
.
.
.
}

dependencies {
    ...
}

def props = new Properties()

props.load(new FileInputStream(rootProject.file("keystore.properties")))
android.signingConfigs.release.storeFile rootProject.file(props.keyStore)
android.signingConfigs.release.storePassword props.keyStorePassword
android.signingConfigs.release.keyAlias props.keyAlias
android.signingConfigs.release.keyPassword props.keyAliasPassword

keystore.properties：

keyStore=manamana.keystore_filname
keyStorePassword=manamana_password
keyAlias=manamana_alias
keyAliasPassword=manamana_alias_password

然后我在项目的根目录中拥有密钥库，并且“keystore.properties”被添加到 .gitignore 并且从未签入
