Could you share a screenshot or list of the files in the jEveAssets\data directory

Do you need only files list?

[GoldenGnu]

Sorry, not the .jeveassets\data folder. but, the jEveAssets\data AKA the program folder

It's a bit confusing there is a data folder in both.

Pardon, here it is:

Okay, I know what the problem is now. Thank you very much!

I will have to release a new version to fix it, you can move the jEveAssets folder out of the program folder to fix it temporarily, until I get a new version released.

Thank you very much for the bug report and the help with finding the issue! 👍

Ok, thanks you for keep developing jeveassets.

Seems like this is still an issue?
I'm running into this exception currently.
I'm running it on macOS on a SMB share. I guess locking ain't supported in that way there?
Before v8.0.1 it worked just fine in this setup.

@jjwedemyer
Thank you for reporting that, It's not the same bug.

You're correct, file locking isn't supported over the network on macOS.

The correct way for jEveAssets to handle this is to ignore the error.
However, it should not ignore all IOException errors, only your specific one,
which means I have to check the exception message, which seems super flimsy.

This will (hopefully) be fixed in the next release.
