If it's 3.5.x, try upgrade to 3.6.x. I had the exact same issue a while back and upgrade maven fixed this, so I didn't bother to debug. That said, it's interesting to understand why we failed under specific version of maven / env, so cc dev list where we have a few maven experts who might be able to help debug.
