AdoptOpenJDK: Lessons Learned from the New Build Farm for Java Itself
summary
Community-run build farm produces nightly OpenJDK binaries for multiple JDK versions, OSes and JVMs (HotSpot and OpenJ9) after being assembled in under a year by 200+ people. It uses Ansible and Jenkins to provision hosts, run pipeline-driven bash/groovy build scripts, and select dynamic build agents, runs ~20,000 tests (JTReg, STF, performance, JCK plans) and publishes signed tarballs to GitHub and adoptopenjdk.net via an API, with mostly green nightly results.
