Netbeans (as RoR editor): Stop the Scanning

I've looked on the Netbeans forums, but they appear to be quite broken. I am about to give up on Netbeans my favorite Rails editor, if I cannot solve this problem.

Netbeans starts scanning projects and never stops, leaving me with no autocomplete nor any other interesting stuff. I have some very large Ruby files (40k lines: they are Excel generated code-files for DB filling), and I'd like开发者_如何学JAVA to exclude them from scanning. Is there any way to do this?

i had the same problem with netbeans , i went to forums and all & they all say it cant be done , i'm currently using text-editors , maybe i'll use radrails or rubymine
