java - Android Studio 'Clean Project' 不工作

Question

我做了什么:

我已将同一个项目('myProject')文件夹(清理/重建没有问题)复制到一个新位置，保留以前的文件夹作为备份，并旨在更改复制的项目以进行更多修改。 *此处项目名称相同，仅位置不同。

然后我在新位置打开我的项目并开始执行。

观察:

当我最初打开 android studios 并导入项目时没有问题，甚至模拟器也在工作。但是当我尝试清理项目时，它显示以下错误。

    Unable to delete directory 'C:\Users\sach\Desktop\Project02\test2\backup20191126\myProject\app\build'
  Failed to delete some children. This might happen because a process has files open or has its working directory set in the target directory.
  - C:\Users\sach\Desktop\Project02\test2\backup20191126\myProject\app\build\outputs\apk\debug
  - C:\Users\sach\Desktop\Project02\test2\backup20191126\myProject\app\build\outputs\apk
  - C:\Users\sach\Desktop\Project02\test2\backup20191126\myProject\app\build\outputs

然后我找到this并尝试了

Gradle > MyProject > app > Tasks > build > clean –

但我仍然收到与下面提到的相同的输出

> Task :app:clean FAILED

    FAILURE: Build failed with an exception.

        * What went wrong:
        Execution failed for task ':app:clean'.
        >Unable to delete directory 'C:\Users\sach\Desktop\Project02\test2\backup20191126\myProject\app\build'

          - C:\Users\sach\Desktop\Project02\test2\backup20191126\myProject\app\build\outputs

错误与我在不清理的情况下尝试重建时的错误相同。

模拟器也在此处工作，但无法清理和重建。 这是同一个项目，名称相同，但位置不同。我想知道为什么会发生在这里。因为在我将其复制到此处之前没有任何问题。请有任何线索摆脱这个。

关闭项目并手动删除文件夹app\build\intermediates
