在 Flutter 中：构建 appBundle 时出错 ->* 出了什么问题：任务 ':app:signReleaseBundle' 执行失败

Question

我正在尝试构建 appBundle 以在 Google Play 上发布我的应用程序。

我有这个错误：

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:signReleaseBundle'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.FinalizeBundleTask$BundleToolRunnable
   > java.lang.NullPointerException (no error message)

* Try:
> Run with --stacktrace option to get the stack trace.
> Run with --info or --debug option to get more log output.
> Run with --scan to get full insights.

* Get more help at https://help.gradle.org

BUILD FAILED in 4s
Running Gradle task 'bundleRelease'...                              5,7s
Gradle task bundleRelease failed with exit code 1

我创建一个密钥：

文件 key.properties：

storePassword=myPassWord
keyPassword=myPassWord
keyAlias=upload
storeFile=./keys.jks

将其放在 android 之前

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

and this inside the android:
signingConfigs {
       release {
           keyAlias keystoreProperties['keyAlias']
           keyPassword keystoreProperties['keyPassword']
           storeFile keystoreProperties['storeFile'] ? file(keystoreProperties['storeFile']) : null
           storePassword keystoreProperties['storePassword']
       }
   }
    buildTypes {
       release {
           signingConfig signingConfigs.release
       }
   }

我遵循https://docs.flutter.dev/deployment/android， 不知道为什么我做错了...

我尝试使用谷歌，但没有成功。重新创建密钥，什么都没有。

Answer 1

我更改了文件以直接放置数据：

   keyAlias "upload"
   keyPassword "myPassWord"
   storeFile file(<path to file>)
   storePassword "myPassWord"

它起作用了。我认为这不是最好的解决方案。

Answer 2

就我而言，我在 android 中将文件命名为错误的

keystore.properties

，并从

key.properties

中选取值。更改名称解决了我的问题。
