Collectible Card Game Headquarters

Hey guys

I found it easy enough to work on other parts of xmage. but whenever I want to make minor changes to cards, it takes me around 45 minutes to compile mage.Sets. then half the time it errors out on cards that I haven't changed (errors below)

does anyone have any tips for a faster development loop?
I have a intel core i7 2.8 ghz 8gb ram, windows 7 sp1. the xmage code is on an ssd drive. I'm using netbeans 8.02
