android - 在根项目 'assembleRelease' 中找不到任务 'android'

Question

我正在使用 Reactnative 0.54.0 和 react-native-cli 2.0.1 以及 gradle 4.8.1

我使用 create-react-native-app myProjectName 创建了一个 react-native 项目

我创建项目的时候没有包含android和ios文件夹，所以我手动添加了。

我还使用 choco 安装了 gradle，然后使用 gradle wrapper --gradle-version 4.8.1 --distribution-type all 为它创建了一个包装器

所以我正在使用 Microsoft vsCode 开发 react-native，然后使用 Genymotion 模拟器查看我的应用程序，一切都很好

现在，我想为 Play 商店生成最终的签名 APK，我使用的是 react-native 提供的指南

https://facebook.github.io/react-native/docs/signed-apk-android.html

当我想运行 gradlew assembleRelease 时出现此错误

C:\myApp\android>gradlew assembleRelease

FAILURE: Build failed with an exception.

* What went wrong:
Task 'assembleRelease' not found in root project 'android'.

* Try:
Run gradlew tasks to get a list of available tasks. 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

assembleRelease 有什么问题？我该怎么办？

要添加更多信息，我不得不说，当我想在 VSTS(TFS Online)中构建这个项目时，我得到了这个错误

2018-07-17T16:20:14.9268702Z ##[error]Error: Not found wrapperScript: D:\a\1\s\gradlew

任何线索都适用 谢谢

更新: 正如@philipp 所问，这是 gradlew 列出的任务列表，而 assembleRelease 不是其中之一!!!!这是什么原因？

C:\myApp\Android>gradlew tasks

> Task :tasks

这是 myApp\android**build.gradle**

project.ext.react = [
    bundleInStaging: true 
]
task wrapper(type: Wrapper) {
    gradleVersion = '4.8.1'
}
android {
    defaultConfig {
        applicationId "com.sunkime.client"
    }
    signingConfigs {
        staging {
            keyAlias = "staging"
            storeFile = file("my-release-key.keystore")
            keyPassword = "qwert%$#@!"
            storePassword = "qwert%$#@!"
        }
        release {
            if (project.hasProperty('MYAPP_RELEASE_STORE_FILE')) {
                storeFile file(MYAPP_RELEASE_STORE_FILE)
                storePassword qwert%$#@!
                keyAlias qwert%$#@!
                keyPassword qwert%$#@!
            }
        }
    }
    buildTypes {
        debug {
            applicationIdSuffix ".debug"
        }
        staging {
            applicationIdSuffix ".staging"
            signingConfig signingConfigs.staging
            minifyEnabled true
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }

        release {
            applicationIdSuffix ".release"
            signingConfig signingConfigs.release
            minifyEnabled true
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
        }
    }
}

我也用过gradlew clean，没区别

Answer 1

它是特定于 assembleRelease 还是 gradlew assembleDebug 有效？

也许试试 cd android && ./gradlew clean && ./gradlew assembleRelease

发布您的应用 build.gradle 也有帮助。

作为第一个任务，我建议运行 ./gradlew tasks 来检查 gradle 是否设置正确以及是否列出了任务 assembleRelease。
