Re: proxy error in update plugin in NetBeans - MOA

[Peter Reutemann]

If NetBeans complains about not being able to update one of its own plugins then it looks like you have a problem with your internet connection. Are you behind a proxy instead if having a direct internet connection?

NB: I'm not a NetBeans user, I use IntelliJ IDEA.

Cheers, Peter

You still seem to have internet connection issues. Maven cannot download the MOA dependencies.

Are you behind a proxy for your internet connection?

Cheers, Peter

but after solving it I have this error

Seems like a permission problem to me. Do you run the build with
different users, one being an administrator and the other not?

NB: I don't use Windows.

Hello, please I need help with how to use concept drift tab in determine which classifier and which concept drift type use 

I am waiting for response please 

[Peter Reutemann]

This is no longer a "dev" question, but a "user" question (ie a post
on the other MOA mailing list). Personally, I don't use MOA at all,
but was only involved on the software engineering side of things.

Cheers, Peter
