NetBeans background scanning projects takes too long

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 reinstalled windows, install the same version of NetBeans 7.2, and it works to slow.

Answer 1

Having the same issue with 8.0.2 when a project has JS resources I tracked it down in my case to a problem with the javascript2 editor module which has been updated over the original version shipping with netbeans 8.0.2.

I simply solved it by removing the updated module.

On Linux:

rm ~/.netbeans/8.0.2/modules/org-netbeans-modules-javascript2-editor.jar

However, after letting the netbeans updater download the module a second time, the problem didn't appear again.

In Netbeans 8.1, the location of this file is at: ide/modules/org-netbeans-modules-javascript2-editor.jar.

Answer 3

After latest update of Netbean 8.0.2 I have the same problem that scaning process did not stop and go forever with CPU usage on 25%.

When I replace javascrip editor files in C:\Program Files\NetBeans 8.0.2\ide\modules on Windows 7 with old one then scaning project process start work again. You can take those file from this repo.
