I have taken upon a project that his hosted on Openshift, from what I have found it currently uses the Jbossews cartridge and has Java 7 installed.
I wish to upgrade to Java 8 but cannot seem to find a way.
I have tried to manually download the JDK, extract and export JAVA_HOME on the start and pre_build hooks and no luck.
To be honest, I am not even sure if my hooks are even being run, I'm not sure how I can check that.
I can't seem to find anything on Openshift themselves.
