使用VsCode和ADV或真实设备"Gradle task assembleDebug failed"

Question

VsCode的调试模式不再启动应用程序，无论是通过AVD还是真正的android设备。直到昨天，我都习惯于完美地处理这两个问题。

我收到一个错误

在调试模式下在为x86构建的Android SDK上启动lib\main.art。。。

渐变任务程序集调试失败，退出代码为1

退出(sigterm)

我运行了扑动医生-v

我不得不说，我完全不知道出了什么问题。

我认为这与代码无关，是不是我没有对我的项目做出巨大的影响性更改。除了调试控制台中的那个错误之外，它没有向我抛出任何其他东西。

编辑2：感谢Siavash对"；扑动干净"；。它解决了问题！

仍然对"；为什么"；这个问题的tho。

Answer 1

感谢Siavash：flutter clean，从项目文件夹内部解决了问题(或者简单地使用VSCode终端)。

Answer 2

这里我有一个答案。请参见以下步骤：-1-转到保存的flutter文件夹，运行"flutter_console.bat"文件。控制台将打开。2-类型"；扑动医生"：-3-它将显示颤振设置中的所有问题。在我的情况下，你可以看到：-

医生摘要(要查看所有细节，请运行扑动医生-v)：

[√]Flutter(Channel stable，1.22.5，在Microsoft Windows上[版本10.0.19042.685]，locale en US)

flatter_run

[！]Android工具链-为Android设备开发(Android SDK版本30.0.3)X找不到Java开发工具包(JDK)；您必须在PATH中设置环境变量JAVA_HOME和JAVA二进制文件。您可以从以下位置下载JDKhttps://www.oracle.com/technetwork/java/javase/downloads/.

[！]Android Studio(未安装)

[√]VS代码(版本1.52.1)

[√]连接的设备(1个可用)

医生发现了两类问题。

基本上，我的错误是关于Java的，在遇到这个错误之前我还没有安装。

希望这会有所帮助。：)
