Project mention: Mill: A Better Build Tool for Java, Scala, & Kotlin | news.ycombinator.com | 2025-07-16
Reading these comments I'm always amused by how different people/teams have radically different needs & preferences, and how other people seem to be dismissive of those. "I don't need anything more than maven", "maven is too slow", "if it's not bootstrappable I don't want it", "there should only be one ultimate build tool", "I hate programming my build", etc.
These opinions are all valid, but only if they don't discount the validity of other strategies. There is no universal law of optimal build practices. There are cases where build performance is critical, and others where it's not. There are cases where configurability is important, and there are cases where it's not. Etc.
Personally, I love having a programmable build in plain Java, which is why I enjoy bld [1] these days. I'm probably the only person you'll ever meet who actually enjoyed using ant, so you're welcome to take my opinion with as much salt as you need to digest that.
