Maven "Threads" option doesn't work

Hi everyone,

I noticed that using the "Threads" option in the maven plugin's defintions doesn't do anything when I'm doing maven builds from within intellij using the Execute Maven Goal option.

First, I can see it doesn't add anything to the command line and second I see the build time doesn't reduce.

If however, I manually add "-T 2c" to the maven command the build time greatly improves.

I'm using Idea 13.1.5.

Thanks,

Guy
