Stack: With git repo package, "removeDirectoryRecursive: permission denied (Access is denied.)" Windows 10

[Osager]

Hello

I have added this in my stack.yaml

- location:
    git: https://github.com/bos/aeson.git
    commit: 4de5a203eeeea593457bc92bc40062f3ea830426

The purpose is to use a aeson version that fixed one bug which is not yet supported in LTS-4.1(my version)

Then when i stack build, i got the error
removeDirectoryRecursive: permission denied (Access is denied.)

Potentially also related: #1917

@Osager can you post a more complete log?
I also wonder: why are all those folders read-only? What's up? Is it somehow stack's fault?

[Osager]

Thanks everyone
I've switched to LTS-6.10 and circumvent the issue

I have a similar issue. Yesterday I installed a git-related package for the Atom editor. Everything worked fine. Today, impossible to run stack in the project folder. I'm lost. I don't know whether this is related to git or to another Atom package such as haskell-ghc-mod, which causes strange things too.

[stla]

I've just removed git from the path and it works now. So this is related to git.

[Blaisorblade]

Again: can somebody try a failing command with the -v option and post the log?
This seems now a duplicate of #2426 but it would be good to confirm.

I've just thought about something strange. I had something like this in stack.yaml:

packages:
- '.'
- location:
   git: https://github.com/qrilka/xlsx.git
   commit: 420e16ca238df80f9bb226d3f9c065463ccdc3e2
  extra-dep: true

Yesterday, at a moment when git was not in my path, I had this misleading message: https://github.com/commercialhaskell/stack/issues/2420.

Then I put git in the path and everything worked fine.

Today stack install/build/exec -- ghci does not work when git is in my path.

I've just done a test: I've deleted the folder .stack-work/downloaded. Then, after deleting this folder, I can run stack while git is in my path. And I observed that after running stack exec -- ghci, the github link in stack.yaml has been downloaded again in .stack-work/downloaded, the folder just deleted.

Therefore, it seems that stack tries to delete this folder when git is in the path. And we get the message removeDirectoryRecursive: permission denied (Access is denied.) because this folder is not empty.

IIRC in some cases stack deletes checked out repos to reclone them (if updating fails for instance). Per #2426 that can fail because some files are read-only. Still, logs with -v would be useful to know what happens instead of guessing.

[stla]

stack -v ? Ok, I'll try next time I have a problem. Now, after the update of the github repo, stack works whether git is in my path or not.

[Blaisorblade]

@stla Yes. More precisely, if say stack build fails, please attach the log of stack build -v.

Here is one log:

Closing as an old need-repro. Feel free to re-open if it's still a problem.

[stla]

It never occured anymore for me (maybe after I updated stack).
