Check out Patches Continuous integration and test by community’s heterogeneous build farm Notify * Spec-driven development Java compliance and implementation compatibility Unit tests enhance and clarify specification Anomalies and ambiguities worked out with the community Tell the dev list what you are doing early and often Submit small patches frequently Don’t tell people they must apply your patch! There’s plenty of work for everyone! * Centralized infra – Distributed build / test Apache infrastructure for code repository, bug tracking, patches, Developers typically work in local mirror and manage patches to JIRA Master code base continuously built and tested by community Supported platforms are those that are actively maintained by community * Software Engineering Support all-comers from command-line to IDE Jupiter – Eclipse plugin for code review FindBugs – static code analysis Use the best tools for the job Binary snapshots posted regularly on website * flexible architecture * Java development tools * pluggable GC architecture * Wiki-based knowledge management * compatibility is king * OSGi modularity * community over code * translation services technical writing website design C/ C++ programmer performance engineering Java programming algorithm design memory management Linux / Windows / etc… programming testing tooling compiler writing build / release management Running Eclipse on Harmony  Harmony passes >98% of Eclipse test suite on Windows and Linux x86  Many Harmony developers are self-hosting development using Eclipse JDT  Harmony is a viable open source runtime for Eclipse RCP applications Developing Harmony using Eclipse  Our repository contains Eclipse metadata for class library development  PDE and JDT enhanced for developing core Java library code  Plug-in available for “Harmony VM-type” JRE layout Writing Unit Tests Specification Reading Post intentions on the dev list Send patch and discuss problems on dev list Coder Writing implementation SVN Server contributors Check in/out Apache infrastructure iterate progress Class library Kernel classes (Java)
