android - 任务 ':sqflite:createFullJarDebug'的执行失败

Question

在flutter应用程序上工作时，升级flutter后，我遇到了sqflite的问题。 (path_provider遇到了同样的问题，但用path替换了它。)
我也尝试过flutter clean。
错误:

FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':sqflite:createFullJarDebug'.
> java.nio.file.NoSuchFileException: C:\Users\fayem\AndroidStudioProjects\myapp\build\sqflite\intermediates\library_java_res\debug\res.jar

* 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.

首先，运行flutter clean，然后，如果不起作用，请删除此缓存目录:

C:\Users\YOURUSERNAME \ .gradle\caches
