【问题描述】：

我正在尝试以签名模式（即 playstore Google）构建这个项目，以便我在学校宿舍的其他朋友可以下载和测试，我尝试了很多文档，但我没有工作请帮助我，这是gradle(build.gradle)

    def localProperties = new Properties()
    def localPropertiesFile = rootProject.file('local.properties')
    if (localPropertiesFile.exists()) 
    localPropertiesFile.withReader('UTF-8')  reader ->
        localProperties.load(reader)
    
    

    def flutterRoot = localProperties.getProperty('flutter.sdk')
     if (flutterRoot == null) 
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the       local.properties file.")


    def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
   if (flutterVersionCode == null) 
    flutterVersionCode = '1'


    def flutterVersionName = localProperties.getProperty('flutter.versionName')
    if (flutterVersionName == null) 
    flutterVersionName = '1.0'


apply plugin: 'com.android.application'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"

   def keystoreProperties = new Properties()
   def keystorePropertiesFile = rootProject.file('key.properties')
   if (keystorePropertiesFile.exists()) 
       keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
   

   android 
         compileSdkVersion 29
   

 

    lintOptions 
        disable 'InvalidPackage'
        
    

    defaultConfig 
        // TODO: Specify your own unique Application ID (https://developer.android.com/studio/build/application-id.html).
        applicationId "com.thealphamerc.flutter_twitter_clone_dev"
        minSdkVersion 20
        targetSdkVersion 29
        versionCode flutterVersionCode.toInteger()
        versionName flutterVersionName
        testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
        multiDexEnabled true
    

       signingConfigs 
       release 
           keyAlias keystoreProperties['keyAlias']
           keyPassword keystoreProperties['keyPassword']
           storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
           storePassword keystoreProperties['storePassword']
       
   

   buildTypes 
       release 
           signingConfig signingConfigs.release
       
   

     

flutter 
    source '../..'


dependencies 
    testImplementation 'junit:junit:4.12'
    androidTestImplementation 'androidx.test:runner:1.1.1'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.1.1'
    implementation 'com.android.support:multidex:1.0.3'

apply plugin: 'com.google.gms.google-services'
   And here is the error in terminal

FAILURE: Build failed with an exception.

    Where:
    Build file 'C:\Users\MTGSTCKN\Documents\flutter_twitter_clone\android\app\build.gradle' line: 39

    What went wrong:
    A problem occurred evaluating project ':app'.

    Could not find method lintOptions() for arguments [build_8bee7k9ov9n3733ekoixc4hsh$_run_closure3@7fad45fd] on project ':app' of type org.gradle.api.Project.

【问题讨论】：

你生成你的密钥库文件了吗？

【参考方案1】：

您的 build.gradle 在发布时应如下所示

查看文档：Official documentation

def localPropertiesFile = rootProject.file('local.properties')
if (localPropertiesFile.exists()) 
    localPropertiesFile.withReader('UTF-8')  reader ->
        localProperties.load(reader)
    


def flutterRoot = localProperties.getProperty('flutter.sdk')
if (flutterRoot == null) 
    throw new GradleException("Flutter SDK not found. Define location with flutter.sdk in the local.properties file.")


def flutterVersionCode = localProperties.getProperty('flutter.versionCode')
if (flutterVersionCode == null) 
    flutterVersionCode = '1'


def flutterVersionName = localProperties.getProperty('flutter.versionName')
if (flutterVersionName == null) 
    flutterVersionName = '1.0'
