Probably the number one thing I have always hated about Java is its build tools. Maven has never really made any sense to me and I simply don't want to have to deal with XML in 2018. Gradle requires me to use a totally different programming language just to write configuration. Ant is somehow more confusing than Maven but less standardized (and is almost useless without Ivy). It's been a few years since I wrote any Java so maybe there is something newer and better, but I just can't bring myself to go back to the misery of reading through that shit just to get a project to compile.

With Go it feels like all you need is a dependency manager and maybe a Makefile for more complex builds.
