Product Version: NetBeans IDE Dev (Build 201507280002)
Java: 1.8.0_51; Java HotSpot(TM) 64-Bit Server VM 25.51-b03
Runtime: Java(TM) SE Runtime Environment 1.8.0_51-b16
System: Windows 8 version 6.2 running on amd64; UTF-8; pl_PL (nb)
User directory: Z:\NetBeans\User\dev
Cache directory: Z:\NetBeans\Cache\dev

I have my cachedir on a RAM disk to improve NetBeans performance and responsiveness. It works great and doesn't require a lot of memory (512MB is usually sufficient). My ramdisk software dumps it's contents to hard disk on shutdown and reloads it on startup.
But the problem appears when I try to open a maven project - NetBeans downloads an index and unpacks it to the mavenindex directory inside the cache directory, filling up my ramdisk completly, and making it unusable.
The idea is to provide an option to store mavenindex somewhere else, in a user provided directory. It could be a startup parameter, similar to --userdir and --cachedir, for example --mavenindexdir.

In my opinion, this must be an option in the user interface, with a big warning next to it saying this folder may grow to ridiculous sizes. I only found out today about this folder, by accident, because my system partition was full: turns out the mavenindex folders of just 2 NetBeans installations take up > 25GB, i.e. over a third of my system partition.
