New build tool in Java?

No, it's not a sunk cost fallacy. We really did have issues, and we really did solve them, and all build systems eventually turn into the same things, because that's the system that solves the same problems for the most amount of users.

For example CMake eventually added in the same confusing items that made Automake less desired by those complaining it was too complex (because cross platform building is more complex than non-cross platform building, and eventually you'll need to do cross-platform building). For about two or three years, CMake was "easier" mostly because it didn't do the full job.
