-repository under `.openshift/action_hooks`:

-The basic model is to:
-
-1. Ensure Java and your build tool are installed remotely, e.g. using a `pre_build` hook
-   (Java and Maven are installed by default, Gradle is not)
-2. Use a `build` hook to build your jar (using Maven or Gradle), e.g.

-	#!/bin/bash
-	cd $OPENSHIFT_REPO_DIR
-	mvn package -s .openshift/settings.xml -DskipTests=true
