NetBeans can't delete that file for some reason. You could try to restart your system to make sure all file locks are released, then remove this folder: C:\Users\spamm\AppData\Local\NetBeans\Cache\21.

Once done NB should hopefully work again.

@mbien stamp file aspect is odd, but this looks more like the issue fixed in #7334

@neilcsmith-net you are right. It was my first thought too but I got distracted by the exception in the log. nbjavacapi module isn't loaded so its the same symptom.

@cho-mik this issue is fixed in NB 22 which should be available next week. If you want to use NB 21 till then, try resetting your config in C:\Users\spamm\AppData\Roaming\NetBeans\21. Once you start NetBeans again, create a new maven project right away without opening the plugin manager or the options and all modules should initialize properly.

Yes, after the restart it works. Thank you.
