Kotlin 无法删除部分子项.这可能是因为进程打开了文件或将其工作目录设置在目标目录中

For some unknown reason, whenever I run gradle clean build after I start my notebook it works as expected. When I try for the second time, I always get

Unable to delete directory 'C:\_d\mycompany\WSs\demo\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.

I found someone failing quite similar problem but using Android Studio/Ubuntu (I am using IntelliJ Community/Windows 10): other question

我仔细地try 了所有的建议，但没有一个能解决我的问题.我只有在重启Windows并只工作一次的情况下才能让它恢复工作.

Some of the recommendations are:

1 - Close the studio and go to the path the issue is located at and delete the folder there. I tried close IntelliJ and I can't delete the folder straight

2 - File > Settings > Build, Execution, Deployment > Instant Run > Uncheck this Check box (Enable Instant Run to hot swap code) There is no such optional in my IntelliJ

3 - gradlew clean Same issue

4 - right-click on the directory, click properties on the context menu that will appear, then uncheck the "Read Only" attribute. After that, click the "Apply" to apply changes. I am administrator but I couldn't change such folder attribute.

5-在windows中以管理员身份运行android studio对我来说很有用.

I didn't find how fix it. Now is happening with a project I have just cloned from micronaut

And I can't delete build folder although I am Windows administrator
