"Access is denied" error running lein source-deps

[kenny-evitt]

I'm trying to run lein source-deps for this sub-project. I'm running versions 2.2.0, 2.5.1, and 2.5.2 in Windows Command Prompt, Cygwin64 Terminal, and Git Bash (respectively). All attempts output (basically) the same result below.

To reproduce, you should be able to clone the above-linked repo and then run, from the root repo directory:

$ cd lein-light-nrepl
$ lein source-deps

Output I'm seeing:

I'm not familiar with how mranderson works internally, but I tried this on my debian machines and it works fine here with any lein version >= 2.4.3.

I'm guessing, considering "(Access is denied)" pops up in the error message, that it's an issue with directory permissions. Either that, or maybe there's some issues with the file name encoding on Windows. Perhaps it's worth ensuring that the directories referenced in the message has the right ACLs, so that you mranderson can write the files it wants to?

(Is there any reason we should believe this is a bug with Lein itself, rather than the plugin?)

[kenny-evitt]

@hypirion I think you're right that it's a permissions issue but I'm also trying to reproduce it on another machines and in other environments, and using a new clone of the repo too, so there's no reason to believe this a bug with Leiningen itself. I'll reopen if I uncover any evidence that it might be.

[kenny-evitt]

It's not a bug with Leiningen. I was able to run lein source-deps as described above in a clean clone using version 2.5.1 on a Mac OS X box. I suspect I can do the same on the original Windows box too.

Alright, thanks for keeping us posted =)
