Jenkins complains of null M2_HOME

I tried to turn on the automatic tool installer for a maven package on Jenkins 1.427, and was rewarded with the following in the build log. It's as if it's reading some but not all of the auto-install config.

I had set up a tarball of maven that lacked the toplevel directory, and this confused Jenkins.
