问题描述
当我在Android Emulator上运行flutter应用程序时，它运行时没有错误，但是当我在移动设备上运行它时，它在调试控制台中显示了以下错误:
When I run my flutter app on Android Emulator it runs without errors but when I am running it on my mobile device it shows following error in Debug Console:
以调试模式在HD1901上启动lib \ main.dart ...失败:构建失败，并出现异常.
Launching lib\main.dart on HD1901 in debug mode... FAILURE: Build failed with an exception.

推荐答案
已解决，只需删除C:\ Users \ .gradle \中".gradle"文件夹中的所有内容即可.如果显示文件已打开并且无法删除，则只需打开任务管理器，转到详细信息"选项卡并找到"java.exe"右键单击每个"java.exe"，然后单击结束进程树".所有java.exe进程结束后，返回".gradle"文件夹并删除所有内容.就是这样.:)
Solved, just delete all the contents in the ".gradle" folder located in C:\Users\.gradle\ If it shows that the files are open and can't be deleted, just open Task Manager, go to Details tab and locate 'java.exe' Right click on each 'java.exe' and click End process tree. After all the java.exe processes are ended, go back to ".gradle" folder and delete all the contents. That's it. :)
