  1. 1. Beyond Ant & Maven: System Centric Java Development with Z2 Henning Blohm ZFabrik Software KG Submission #188
  2. 2. The z2-Environment is a radically new approach to solution life cycle management in Java 2
  3. 3. Motivation > Get rid of Build & Deploy No out-of-sync Build infrastructure No missing secondary assembly description No incomplete deployments > Fix the Integration Leak: Make sure you get the latest - always Isolation as exception > Simplify life-cycle operations: Develop & Fix Scale out In other words: Improve solution life cycle handling 3
  4. 4. The Trouble w/ Build Systems Local Build environments… > > > > > > Are complex to maintain and debug Hold solution artifacts in the wrong place Repeat structural information of the solution Decouple Runtime from Solution definition Make it hard to start something new… Imply non-trivial investment in production infrastructure 4
  5. 5. Leaking Integration Runtime > > > > You The Truth Solutions evolve from small and simple to large and modular Solution!=infrastructure => Distributed complexity Sync & Build & Deploy error prone => Developers defer integration Runtime!=Truth => You are on a deadly non-integration vector! 5
  6. 6. Fixing the Integration Leak 1. Pump! – – – Add infrastructure on the side to validate and support E.g. Continuous Integration w/ ANT or Maven (+Repos) et al But the following seems to be the case: 2. Plug the leak! – Z2-Environment 6
  7. 7. How does Z2 work > > > > The Z2 runtime loads updates directly from the SCM Compilation (e.g. for Java) is done by the runtime when necessary Local override from workspace for local development The whole solution defined in one repository structure == a System We call it a System-Centric approach
  8. 8. Travel Portal: About ~250 kLoJC, 7.5kLoJSPC DEMO 8
  9. 9. Z2 Integrations > Z2 with Spring – Spring for the in-module wiring – Z2 for the cross-module wiring > Z2 with Hadoop – Map/Reduce jobs as integrated componens – Full cross-module re-use > Z2 with Quartz – Jobs as integrated components > ... You get the point. 9
  10. 10. What Z2 is not… > Z2 is no replacement for Maven – Maven is for many smallish independent projects that want to re-use – I.e. it’s Apache > Z2 is not useful for library development – Unless it’s a tool based on the solution – … Z2 is really for solution development (once more…) > Z2 is no build tool – It is possible to download binaries – Useful for e.g. automated, scheduled Unit Tests 10
