Chapter 12: Broken link to clojure

[Grazfather]

The link in the java chapter is broken: It mixes up 1.7.0 and 1.9.0, and it doesn't use https. The link should be https://repo1.maven.org/maven2/org/clojure/clojure/1.9.0/clojure-1.9.0.jar

Then the command after it should be updated (to point to 1.9.0) and the output of MANIFEST:

Manifest-Version: 1.0
Archiver-Version: Plexus Archiver
Created-By: Apache Maven
Built-By: jenkins
Build-Jdk: 1.7.0
Main-Class: clojure.main
