【中文标题】Flutter：在根项目“android”中找不到任务“assembleStageDebug”【英文标题】：Flutter: Task 'assembleStageDebug' not found in root project 'android' 【发布时间】：2020-11-10 15:34:06 【问题描述】：我正在尝试在 android 设备上使用颤振制作的应用程序，当我尝试在手机上运行该应用程序时，我收到以下错误 “在根项目 'android' 中找不到任务 'assembleStageDebug'。”
我的应用在 ios 上运行良好，但在 android 上运行时，它会导致问题。颤振医生没有发现任何问题，似乎没有人和我有同样的问题。我首先面临“不支持的Android插件版本：4.0.1”的问题。我被告知通过运行 -> 编辑配置 -> 风味添加风味并将名称添加到风味并使用 flutter run --flavor "flavor_name" 运行应用程序，这导致了此错误。提前致谢！
错误信息

* What went wrong:
Task 'assembleStageDebug' 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.

[!] Gradle project does not define a task suitable for the requested build.
The android/app/build.gradle file does not define any custom product flavors. You cannot use the --flavor option.

【问题讨论】：
我以前也遇到过同样的问题。我做了颤振升级，它解决了问题。 【参考方案1】：我的问题是我在根项目下没有 settings.gradle 所以，在根项目下添加该文件并在其中添加这一行
include ':app'
希望它有效。
【讨论】：
【参考方案2】：问题是因为你在android/app/build.gradle/中没有提到flavorDimensions
我希望您已经为您的项目正确创建了flavor。如果没有，请阅读这篇文章和set up your flavor。
设置您的flavor 后，您需要将此代码添加到android/app/build.gradle/ 的android 部分。
flavorDimensions "default"
productFlavors
dev
dimension "default"
versionNameSuffix "--dev"
stage
dimension "default"
versionNameSuffix "--stage"
prod
dimension "default"
将此作为您的代码
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 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'

运行flutter clean 并重新运行应用程序，它将被修复。
【讨论】：
【参考方案3】：使用 android studio 运行 flutter 尝试进入你的项目结构并将项目 SDK 更改为 Android API 27 平台然后应用并重新运行应用程序
【讨论】：
【参考方案4】：试试：
flutter upgrade
然后
flutter run -v
这对你有帮助
