NetBeans should not scan jars for deactivated plugins

When I deactivate plugins, they will still be inside the folder C:\Users\Chrl\AppData\Roaming\NetBeans\8.2\modules. When opening NetBeans I got over 100 warnings of dependencies that will upgraded:

WARNING [org.netbeans.core.modules]: had to upgrade dependencies for module arduino: added = [module org.netbeans.modules.projectuiapi.base/1 > 1.78.0, module org.openide.filesystems.nb, module org.openide.filesystems.compat8] removed = []; details: [Separate projectuiapi into desktop and NetBeans independent and dependent parts, Separation of desktop and cleanup]

So yes I installed arduino but I deactivated it. I deactivated a lot more like ruby and atmel and all are scanned. So for me, I don't want to deinstall those plugins, because I will loose the history of all plugins that I added months or years ago.

So in my understanding, netbeans scans all jars inside of the modules folder and this takes time. Not that much, maybe some ms but if you have 150 addons installed, like me and NetBeans needs round about 20ms for that jar to scan at starting the IDE and give the warning, doesn't matter whether it is activated or not, it will increase the starting time. So 150 * 20ms = 3s. Of course this is not much but preventable.

I would prefer to move deactivated plugins into a sub folder called deactivated and exclude them from scanning, if this is possible, How does that sounds?
