Core Development Tools Update Java 9, Jenkins, Maven… Will Iverson Co-owner, Dev9

• Will Iverson • Co-owner, Dev9 • Professional software dev/ architect/consultant since 1995 • Roles: Apple, Symantec, SolutionsIQ • Clients: Sun, BEA, Canal+, T-Mobile, at&t, Microsoft, State of WA, many other local firms… • 4 books, many articles

• 2015 – VR, 20 Years of Java & CMS • 2013 – Greenfield Java • 2012 – JPA/Hibernate & myBatis • 2011 – Session Management, Selenium • 2010 – Play Framework • 2010 – CSI: Java - Dead JVM Analysis • 2009 – Maven • …

• Where are things with Java 9, Jenkins 2, and Maven? • In this session we'll look at the status of the major updates to core development tools, including (where applicable) demos of the current releases. • We'll also cover some simple scenarios for using Docker to ease development tasks, even if you aren't ready for Docker in production. • We'll conclude with a review of what it means to be a "full stack developer" in a world of advanced JavaScript, mobile, voice, virtual reality, and more.
