So who/what is using the ant build? I thought it was just the IDEA project that generated ant targets. Is it run explicitly using ant by langtool developers? I know for sure it's not used when we build the product in our CI.
As Jan mentioned, the main purpose of the langtools Ant build is to get very very fast incremental recompilation. Which happens to be very useful when working in an IDE environment, but one can also use it (and I've seen people doing that) just from the command line. You can run most (all?) of langtools tests by just doing a private langtools build, so langtools developers sometimes go down that path.
Now, to be fair, this was much more common in the non-consolidated world than it is in the new world, but, as Jan mentioned, Make is currently not useful as a replacement for the private langtools build because it has to go through the interim step and all that - and doing that, even in the face of one line change in one file was taking approx 15s recompilation time back when I did the test. So the private build still has a purpose.
