在颤抖的情况下两次构建应用程序后，构建失败 [英] Build fails after 2 times build of the application in flutter

问题描述

用VS代码构建Flutter应用程序后，我成功运行了该应用程序，一切正常.但是在重新启动应用程序两次或更多次之后，每当我再次运行代码时，构建都会失败.这是错误弹出.

After building my flutter application in VS code, I successfully run the app, everything works fine. But after 2 or more times of restart of the application, whenever I run my code again, the build gets failed. This is the error pops up.

Target debug_android_application failed: FileSystemException: Cannot copy file to 'J:\flutter_projects\webdoc\build\app\intermediates\flutter\debug\flutter_assets\assets\images\background.png', path = 'J:\flutter_projects\webdoc\assets\images\background.png' (OS Error: Access is denied.
, errno = 5)
build failed.

FAILURE: Build failed with an exception.

* Where:
Script 'C:\src\flutter\packages\flutter_tools\gradle\flutter.gradle' line: 780

* What went wrong:
Execution failed for task ':app:compileFlutterBuildDebug'.
> Process 'command 'C:\src\flutter\bin\flutter.bat'' finished with non-zero exit value 1

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Running Gradle task 'assembleDebug'...
Running Gradle task 'assembleDebug'... Done                        10.2s
Gradle task assembleDebug failed with exit code 1

第一次发生此错误时，我从当前目录中剪切了所有文件，然后将其复制到其他目录中，然后再次正常运行.但是即使现在再次运行2或3次后，仍会弹出错误.有没有针对此问题的修复程序?

When first time this error has occured, I cut all the files from the current directory and copied into other directory, and then it works again fine. But even now after running 2 or 3 times again the error pops up. Is there any fix available to this problem?

我尝试删除.vscode，然后重新构建，但仍然相同！

推荐答案

在更新flutter之后，我遇到了同样的问题，我删除了flutter SDK，然后再次下载并解决了问题.

I had the same problem after updating flutter, I deleted the flutter SDK and downloaded again and the problem solved.
