hey all, I'm getting the following error when trying to build a project via SBT in scala

```
[info] :: USE VERBOSE OR DEBUG MESSAGE LEVEL FOR MORE DETAILS
java.lang.IllegalStateException: impossible to get artifacts 
    when data has not been loaded. IvyNode = log4j#log4j;1.2.14

```

I don't see any of my projects referencing 1.2.14, nor is it in my .m2 or .ivy repositories. Not sure where to look for this one

a full error dump is here: <http://pastebin.com/pM7NUhY0>

thanks
