Hi Frank,

Saying 'Hi' and 'Thanks' is appreciated.

Could you precise if the error is reproducible if you try to update binding again, or if you encountered it only once (could be a race condition)?

Hi,

I confirm this problem tends to happen easily, though it's not clear how to reproduce. I created a ticket to track: https://jira.sonarsource.com/browse/SLE-128

I will update the ticket (soon) with a workaround to get out of the broken state until a definitive fix is ready.

Cheers,

Janos

Hello,

I am facing same issue and I see issue is related to permission to some metadata file. Before talking anything more, first here is exception stacktrace.

I see it comes because one of the file under server_issues folder has no permission even for admin user. When I see file properties/security tab, I see no user has read permission on that file (including admin) and I can't see owner also (Windows 10 machine). Now error comes when I update all project bindings, Sonarlint tries to delete module folder and create new one. During delete process, it is not able to delete that particular file (I see similar files in some other folders like 1/f/  2/b not giving that issue). Another point to note is, when I close eclipse, that file automatically gets deleted.  Note that however, module delete operation during update bindings, deletes configuration.pb of that module. So after that every time automatic analysis runs, it says couldn't find configuration.pb file. And then I don't have any other option but to close eclipse and delete whole module folder and rebind project (without closing eclipse can't delete module folder).

Hope this helps in analysis.

Regards,

Alpesh

Hi,

As you can see on the ticket I linked earlier in the thread (https://jira.sonarsource.com/browse/SLE-128), this fix is scheduled for the 2.5 release, coming up soon. Until then, if this happens, I'm afraid you have to close Eclipse and manually delete the problematic directory.

yes fine. My point was just to provide additional information that this file which is not getting deleted, even admin has no read permission for that and couldn't see file owner information. So something related to file permission.

Hi Alpesh,

It's interesting that Windows gives a permission denied error in this situation. In fact the issue has nothing to do with filesystem permissions, the underlying problem is file locking. The problem is due to some leaked resources, file handles that were not closed correctly by SonarLint. Closing Eclipse closes those files, and then they can be deleted, by your own user, without permission issues. I hope this answers your question. The 2.5 release is coming very soon.

Cheers,

Janos

Thanks for your explanation.  Yes, I saw that 2.5 is released for feedback and it has already solved my issue. Thumbs up for that.
