Answer 1

Don't bother - found it after making a directory diff :

Stop Netbeans, remove the file underneath and start Netbeans again.

For NetBeans 8.0.2 (in my case):

C:\Users\username\AppData\Roaming\NetBeans\8.0.2\config\Preferences\org\netbeans\modules\java\source\BuildArtifactMapperImpl.properties

Set to true or file can be deleted, to reset.
