Add Maven to Docker Oracle Linux Image

I spent way too much time figuring out how to install Maven on Oracle Linux from behind a proxy. This is the solution I came up with.

Sample Dockerfile

FROM oraclelinux:6

# Uncomment and update if you are behind a proxy
#RUN export http_proxy=http://user:pass@proxyurl
#RUN export https_proxy=http://user:pass@proxyurl

# Install Maven
RUN yum -y install wget
RUN wget -O /etc/yum.repos.d/epel-apache-maven.repo
RUN yum -y install apache-maven

# Uncomment this in order to connect to maven repos
#ADD settings.xml /root/.m2/settings.xml

Sample Maven settings.xml

<?xml version="1.0" encoding="UTF-8"?>
