Projectile find file results in "unable to connect to a repository at url, no more credentials" in svn project

[RKBK]

I suspect this is a configuration problem on my end, but I'm not quite sure how to solve it.

Expected behavior

Files should be findable.

Actual behavior

The error

svn: E170013: Unable to connect to a repository at URL 'https://our/central/repository/project' svn: E215004: No more credentials or we tried too many times. Authentication failed

Steps to reproduce the problem

Inside a project file, invoke projectile (I use C-c p), select projectile-find-file: error results

Environment & Version information

Projectile version information

Projectile 2.3.0

Emacs version

27.1

Operating system

Ubuntu 20.04 under windows subsystem for linux (version 1)

That's the shell command that Projectile uses to obtain the list of project files:

(defcustom projectile-svn-command "svn list -R . | grep -v '$/' | tr '\\n' '\\0'"
  "Command used by projectile to get the files in a svn project."
  :group 'projectile
  :type 'string)

It seems to me the error comes directly from it in your case.

When running just the first part, svn list -R .

I get asked to provide my svn password. Afterwards it asks me to provide a password for a new default keychain. After pressing cancel, a list of all the files in the repository gets dumped to the terminal window.

However, with the full piped command as written above, there is never an option for me to provide my password. So I suppose this is the issue. Does the command assume that you've somehow cached your svn password?

I found that there is such an option in subversion, https://unix.stackexchange.com/questions/191048/how-to-make-svn-save-credentials-when-non-interactive . However, would it be useful for projectile to handle the user supplying a password?

OK, actually, if I allow the first command to create a new keychain, the password is stored. And then, the projectile command works fine. So maybe this is the way to solve it, not by changing projectile.

I guess so. This was done a long time ago and I haven't used SVN in ages, so I don't really remember. We can maybe add some note in the docs for posterity's sake.

I just restarted emacs and ran into the same thing. To be clear, what I end up having to do is:

1. Start emacs
2. Enter eshell (or similar, I assume), M-x eshell
3. Execute command svn list -R .
4. Enter password for keyring in pop up prompt
5. The list of files should appear as output. Projectile will now also work.

I just encountered the same problem. For svn to ask for a password via its password stores interface, I need the flag "--force-interactive" added to the command line. Somehow when svn is run from within emacs, it seems to assume non-interactive mode of operation and it refuses to ask for passwords then.

This is the full projectile-svn-command and it works now:

svn --force-interactive list -R . | grep -v '$/' | tr '\n' '\0'

I already had vc-svn-global-switches configured to "--force-interactive" for Emacs' built-in vc-svn to work. Maybe projectile should honor that variable?

Projectile also does not detect the root of SVN repositories out-of-the-box. I had to put projectile-root-top-down-recurring as first element in projectile-project-root-functions.

Is there a way to re-open the issue now, or should I create a new issue?
