Question

NetBeans background scanning projects takes too long. Every time when I open netbeans it scanning for ages. I used NetBeans 7.2 and it works perfecly. Now I formatted pc and rei

Answer 1

OS: Windows 7 x64.

The following worked for me:

I fully uninstalled Netbeans (ticked all boxes in uninstaller). For those who couldn't you'll need to go to C:\Users\%username%\AppData\Roaming\NetBeans\8.0.2 and delete a file called 'lock'. This is normally removed when the program exits but if you need to force terminate it'll remain there.

After that I uninstalled JDK and JRE then downloaded Java Platform (JDK) 8u40: http://www.oracle.com/technetwork/java/javase/downloads/index.html

And Netbeans 8.0.2: https://netbeans.org/downloads/

Installed JDK (which installs JRE too), after that Netbeans. Once complete I loaded up projects where background scanning got stuck and it seems to have fixed it. Will post updates if it starts happening again.
