I bet my Clojure or Groovy version will be simpler. I agree Scala is super complex :). Maven does suck. Gradle wraps it and does not suck. Probably the best build tool I have ever seen.
So, a more succinct Java, that can't leverage the JVM ecosystem? Why is that better than Scala, which can also be more succinct than Java, but can leverage the JVM ecosystem?
Open the rosettacode web site. Choice any algorithm you are familiar with. Place Go version and Java version. Compare the number of words and lines.
Compare the Maven hell with how Go solves the same problems.
