Could not create task ':app:processDevDebugMainManifest'

问题

以下是您提供的错误消息的翻译：

当我运行Flutter项目并在Gradle构建时遇到此错误：
无法确定任务“:app:processDevDebugManifest”的依赖关系。
> 无法创建任务“:app:processDevDebugMainManifest”。
> 无法调用“Object.toString()”，因为“value”为空

我尝试了以下方法：尝试了很多解决方案，没有帮助，安装了最新版本，运行了flutter clean，flutter pub get，flutter pub upgrade，重新启动了VSCode，重新启动了Windows，比较了这个项目与其他正常工作的项目，比较了AndroidManifest.xml文件，比较了build.gradle 2文件并消除了可能引发此问题的依赖项 - 没有用

最终在CHATgpt的帮助下，我获得了堆栈跟踪，但仍然无法访问Gradle API文件以及其中的类，那么如何进行调试？

很糟糕，我卡住了，而不是编程Flutter - 我在处理这些问题。
为了您的方便，我标记了错误开始的地方，但我不知道如何调试。

任何帮助都将不胜感激！

原因是：java.lang.NullPointerException: 无法调用“Object.toString()”，因为“value”为空
在com.android.build.gradle.internal.core.VariantDslInfoImpl$manifestPlaceholders$2.invoke(VariantDslInfoImpl.kt:854)

  • 异常是：
    org.gradle.api.internal.tasks.TaskDependencyResolveException: 无法确定任务“:app:processDevDebugManifest”的依赖关系。
    在org.gradle.api.internal.tasks.CachingTaskDependencyResolveContext.getDependencies(CachingTaskDependencyResolveContext.java:68)

英文:

when i run flutter project and getting this error on gradle build:
ould not determine the dependencies of task ':app:processDevDebugManifest'.
> Could not create task ':app:processDevDebugMainManifest'.
> Cannot invoke "Object.toString()" because "value" is null

what i have tried: i try so many solutions, nothing helps
intalled latest version, flutter clean, flutter pub get, flutter pub upgrade, reastart vscode,
restart windows, compare this project with other project that works fine, comparing AndroidManifest.xml files, comparing build.gradle 2 files and eliminating posibile dependencies that might cause this issue - N O T H I N G

finally with the help of CHATgpt i got the stacktrace, but still, i dont have access to gradle api files, and the classes inside them, so how can i do a debugg ?

sucks, i am stuck and instead of programming flutter - i deals with this issues.
for your convinience, i marked where the error begin, but again - i dont know how to debugg this.

any help will be highly aprreciated!

请检查在启动Flutter项目时是否使用了类似于“dev”这样的flavor。

英文:

Please check if you are running by using flavor like "dev" when you start the Flutter project.
