Don't turn every language into Java. Plenty of tools will not rebuilt a project if no files have changed, but the dumb, quick and easy way that requires no deendendencies is simply to delete and rebuild. The fact that this functionality is served so well by a simple dependency shows that you don't need overly complex monolithic tools to accomplish small tasks.
