Flutter 应用程序卡在 "Running Gradle task ' assembleDebug'

Question

从 VScode 运行时，我的 flutter 应用程序始终卡在 running-gradle-task-assembledebug

当我在命令提示符下运行 flutter run -v 时，它可以工作，但不能从 VSCode 运行。这个问题似乎从上周就出现了。 尝试过 ./gradlew clean 和 ./gradlew clean 构建，这有时有效并且从 vscode 构建

删除并创建了一个新的模拟器设备，并在线尝试了许多建议

flutter doctor -v 的输出

创建了一个全新的 flutter 项目并进行了 gradlew clean 并得到了以下 gradlew clean --warning-mode all 的消息

> Configure project :app
Adding a Configuration as a dependency is a confusing behavior which isn't recommended. This behaviour has been deprecated and is scheduled to be removed in Gradle 8.0. If you're interested in inheriting the dependencies from the Configuration you are adding, you should use Configuration#extendsFrom instead. See https://docs.gradle.org/6.7/dsl/org.gradle.api.artifacts.Configuration.html#org.gradle.api.artifacts.Configuration:extendsFrom(org.gradle.api.artifacts.Configuration[]) for more details.

从google官方文档重新下载了flutter 2.8 sdk，里面也有dart并重试。

这是由于你的gradle正在下载它的版本，但有时下载速度太慢而无法下载，你可以修复它:

首先检查项目根目录中的 gradle 版本:

<project name> > android > gradle > wrapper > gradle-wrapper.properties

并检查 distributionUrl ，您将看到项目中正在使用哪个 gradle 版本并正在下载，因此您应该在此链接 https://services.gradle.org/distributions/ 中下载该版本。

下载后，复制并转到此目录:

C:\Users\<user name>\.gradle\wrapper\dists\gradle <your version>\<a file with weird name>\

将下载的文件粘贴并解压到此处。

每当我对你抱有希望时，它都对我有用。 如果有任何问题请告诉我。
