It looks like the link for Apache Ant on the build pack is dead. Since, we're going to move to Gradle now. We can use a gradle buildpack that I made while doing GCI. Here's the repo for it: https://github.com/yukiisbored/heroku_buildpack_gradle_loklak

@yukiisbored Nice work! Please merge it to the buildpack repo and rename the repo in loklak. Let's have all project related stuff here.
