WL-2355 Fix so that with a clean repo build works.

Maven 2 doesn't correctly get the order of the build right and doesn't spot out plugin depenendency is available in the reactor. The order is consulted when everything else is equal so moving it first fixes the issue.
Maven 3 doesn't have this issue so it's not required once we upgrade.
