在开发 Flutter 应用程序时，我已经尝试了之前列出的所有修复，但没有任何效果。我相信一切都已正确配置且位于正确的位置，因此我需要帮助找出签名配置仍然引发此错误的原因。我已经尝试了几个小时来寻找另一个没有运气的解决方案。一切都拼写正确。错误如下。

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:validateSigningRelease'.
> Keystore file not set for signing config release

key.properties 文件夹在 android 主文件夹中，upload-keystore.jks 文件在 android/app 中。

key.properties 是

storePassword=xxxx
keyPassword=xxxx
keyAlias=upload
storeFile=/Users/..../android/app/upload-keystore.jks

完整的build.gadle 是

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 plugin: 'kotlin-android'
apply from: "$flutterRoot/packages/flutter_tools/gradle/flutter.gradle"
apply plugin: 'com.google.gms.google-services'  // Google Services plugin

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

【参考方案1】：

好吧，在我用头撞墙一天之后，我想出了这个问题。我的key.properties 文件夹中有一个未知空间，位于引发错误的文件名的开头。因此，如果一切正常，请注意随机空间！

【参考方案2】： 重新生成密钥
