Pull-based Continuous Delivery for Java applications

Prerequisite

• Maven Infrastructure

How

• Cron job to upgrade application (if changed) every 5-30 minutes.

• Cron job triggers a script which will download and upgrade the application if there is a newer snapshot available. If application version is set to a release version and this version is already running, nothing will happen.

• Example scripts
