37 Releasing - One project to build them all! • Idea: Every engineer should be able to build a release candidate • Single repo with Vagrantfile and gradle build • Requirements: Vagrant (+ winrm), VirtualBox, gradle • Vagrant image installs the technology zoo! • Builds projects, creates package repositories (+ signing) and uploads to S3 bucket, uploads to sonatype staging repo • Result: Final immutable artifacts, which are ready to be released
