Unable to Delete Dist Folder from Netbeans’ Build.xml File

I found this weird error when building my java application into jar from Netbeans, somehow Netbeans shows error due to unreadable dist folder. And the weird thing is, i cannot delete the dist folder manually, it keeps giving me the Folder Access Denied dialog box with choices to “Try Again” or “Cancel”. I also have tried changing permissions in the properties window but it does not seem to work.

Well the workaround is actually simple, i just open task manager, and end explorer.exe process. And i dont know why, but my dist folder is gone. Very weird actually 😀
