簽署 android 捆綁包時出錯：任務“：app：signReleaseBundle”執行失敗

Question

我正在嘗試構建 Flutter android 應用程序的發布版本並收到以下錯誤：（使用終端命令的 Macbook M1）

* What went wrong:                                                      
Execution failed for task ':app:signReleaseBundle'.                     
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade
   > kotlin.KotlinNullPointerException (no error message)

我不知道如何解決這個問題。 相關部分的 android/app/build.gradle 如下所示：

    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 {
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version"
    implementation 'com.android.support:multidex:2.0.1'
}

Answer 1

我遇到了幾乎同樣的問題：

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

就我而言，我的key.properties文件中有錯字。 我有keyPasswork而不是keyPassword ，現在一切正常。 我建議 OP 也檢查這個文件。

Answer 2

就我而言，android/app 下的文件build.gradle中有錯字

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

檢查這是否正確。 有時，錯字可能是而不是寫storePassword ，而是寫storeP assword
