IDEA 11 and Maven 3 problem

Hi
I'm using IDEA 11 and Maven 7 on win7 64bit.

For every maven project, I have something below:

[WARNING] Command line option -npu is deprecated and will be removed in future Maven versions.

I understand the -npu command option is related to plugin update. But whether I check the option or not, I got the -npu or -cpu warning.

And download those plugins everytime on every project is really annoying, I can't find a way to disable it.

PS: These won't show up if I use maven directly from command line.
