我的flutter应用程序在从VScode运行时总是停留在running-gradle-task-assembledebug
当我在命令提示符中运行flutter run -v时，它可以工作，但不能从VSCode中运行。这个问题似乎从上周就出现了。尝试了./gradlew clean和./gradlew clean build，它有时可以工作，并从VSCode中构建
删除并创建了一个新的模拟器设备，也尝试了许多建议在线

创建了一个全新的flutter项目，并进行了gradlew清理，并获得了以下gradlew清理消息--警告模式全部

> 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.

        (Run with --stacktrace to get the full stack trace of this deprecation warning.)
The AbstractArchiveTask.destinationDir property has been deprecated. This is scheduled to be removed in Gradle 7.0. Please use the destinationDirectory property instead. See https://docs.gradle.org/6.7/dsl/org.gradle.api.tasks.bundling.AbstractArchiveTask.html#org.gradle.api.tasks.bundling.AbstractArchiveTask:destinationDir for more details.

The AbstractArchiveTask.archiveName property has been deprecated. This is scheduled to be removed in Gradle 7.0. Please use the archiveFileName property instead.
