Hi Andy,
Would you be able to create a small project that reproduces this
consistently that you can share with us? I've been unable to reproduce
this.
Also, if you could raise it as a problem on http://forums.gradle.org
then we can enter it in to our tracker, and that also makes it more
visible to future googlers.
Thanks.

I ran into this exception from gradle. I'm using 1.0-milestone-6. Is
this a known problem? I can provide more support documentation, but
I'm not sure what would be helpful at this point...
Cheers,
Andy
