Backup script fails during update on Windows when paths exceed 260 char limit

[Vonken]

Can't update to new version. Running OpenHab 2.4.0 on Windows. If I run from PowerShell the window is closed at the last point and I was unable to catch the error so I tested from CMD and got this error:

That path seems to exceed the max path length of Windows that is 260 chars according to these docs.

There are 264 chars in:

C:\Users\Familjen i Lerkil\AppData\Local\Temp\openhab\backup-2.4.0\runtime\system\org\eclipse\smarthome\automation\org.eclipse.smarthome.automation.module.script.defaultscope\0.10.0.oh240\org.eclipse.smarthome.automation.module.script.defaultscope-0.10.0.oh240.jar

Perhaps enabling longer paths can be used as a workaround?

Thanks for the answer! Did a fresh install and copied all files and settings but this will propebly help me in the next upgrade or someone else.

This also happens if bundles installed from the marketplace (especially kar-files) are used. The reason is that they easily exceed 255 characters as they are unpacked to <userdata>/tmp/kar/<filename>. Since tmp, cache and backup are removed after copying anyway, this is a bit annoying.
