title: What is the right way to add Maven and Ant to a Jenkins Docker container?
body: <p>I downloaded the jenkins/jenkins:lts image from docker hub which I got up and running on Ubuntu 16.04. The image doesn't seem to include Ant or Maven, and may also want to do builds against different versions of the jdk. I am wondering what is the right way to adress this - can I just run bash on the container and run apt-get or yum as the case may be to install extra stuff needed for my builds, or is there a better way?</p>
