copyDirectories - FileAlreadyExistsException

[dos65]

I don't know how to reproduce but sometimes I'm getting the following error in Metals from bloop and compilation stucks.
Clean workspace doesn't help in this situation.

// after that compilation always fails with the following error

Looks the same as #1989 ? I will take a look at it soon.

@tgodzik yep it the same. Will close it as a duplicate.
