执行flutter build app bundle失败，请求排查解决

已完成的配置操作 #

• 生成密钥库命令：

  keytool -genkey -v -keystore %userprofile%\upload-keystore.jks -storetype JKS -keyalg RSA -keysize 2048 -validity 10000 -alias upload
  

• 创建android/key.properties文件，内容如下：

  storePassword=mypassword 
  keyPassword=mypassword
  keyAlias=upload
  storeFile=d:\key\upload-keystore.jks
  

• 密钥库实际存储路径：d:\key\upload-keystore.jks
• app/build.gradle配置片段：

  def keystoreProperties = new Properties()
  def keystorePropertiesFile = rootProject.file('D:\\passport\\android\\key.properties')
  if (keystorePropertiesFile.exists()) {
      keystoreProperties.load(new FileInputStream(keystorePropertiesFile))
  }
  
  android {
      compileSdkVersion 33
      ndkVersion flutter.ndkVersion
  
      compileOptions {
          sourceCompatibility JavaVersion.VERSION_1_8
          targetCompatibility JavaVersion.VERSION_1_8
      }
  
      kotlinOptions {
          jvmTarget = '1.8'
      }
  
      sourceSets {
          main.java.srcDirs += 'src/main/kotlin'
      }
  
      defaultConfig {
          applicationId "com.raparin.passport"
          minSdkVersion 21
          targetSdkVersion 33
          versionCode 1
          versionName "1.0"
      }
  
      signingConfigs {
          release {
              keyAlias keystoreProperties['keyAlias']
              keyPassword keystoreProperties['keyPassword']
              storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
              storePassword keystoreProperties['storePassword']
          }
      }
      buildTypes {
          release {
              signingConfig signingConfigs.release
          }
      }
  }
  

当前问题 #

执行flutter build app bundle时触发错误：Keystore file not found for signing config 'release'。已确认Java、Gradle、Flutter、keytool及Dart环境配置正常，flutter doctor无任何错误或警告。
