Flutter App 卡在“正在运行 Gradle 任务 'assembleDebug'

Question

从 VScode 运行时，我的颤振应用程序总是卡在 running-gradle-task-assembledebug

当我在命令提示符下运行 flutter run -v 时，它可以工作，但不能来自 VSCode。这个问题似乎是从上周开始的。 尝试了 ./gradlew clean 和 ./gradlew clean build，这有时有效，并且是从 vscode 构建的

删除并创建了一个新的模拟器设备，并在网上尝试了很多建议

创建了一个全新的颤振项目并执行 gradlew clean 并收到以下消息 gradlew clean --warning-mode all

> 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 官方文档中重新下载了 Flutter 2.8 sdk，其中也有 dart 并重试。

Answer 1

这是由于你的gradle正在下载它的版本，但有时下载速度太低无法下载，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

检查distributionUrl，你会看到项目中正在使用哪个gradle版本并正在下载，所以你应该在这个链接https://services.gradle.org/distributions/下载那个版本

下载后复制到这个目录：

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

在此处粘贴并解压缩您下载的文件。

每当我希望你也能做到时，它都对我有用。 如果有任何问题，请告诉我。
