M2E plugin continually updating index

Question

I've installed Maven and the m2e Eclipse plugin. For some reason Eclipse is stuck updating indexes whenever I launch it now. Clicking the link on the operation shows the logs below. How can I stop this operation (stop button doesn't work) or fix this?
