Java Dependency Management with Maven

Maven plays an important part in continuous integration and continuous delivery to speed up the development lifecycle, explains Cesar Hernandez in his article titled "Java Dependency Management with Maven". It is a powerful and mature build automation tool that has become a de facto tool for dependency management in Java projects.

Maven provides many ways to automate the application development lifecycle and the management of Java dependencies for Java projects. A key component of Maven is repositories, places where you can obtain and share dependencies (artifacts). Repositories allow developers to access thousands of tools, libraries, and frameworks from the open source community. Another key aspect of Maven, which has helped it to stay up to date, is its extensive plugin capabilities. To see how to take advantage of this powerful tool, read the article.

New Java Champion Henri Tremblay

Welcome the new Java Champion Henri Tremblay!

Henri Tremblay has been developing with Java since 1998. In 2003, he became a main contributor of  the EasyMock open source project and created the concept of class mocking. He also invented and coined the term "partial mocking". He is now the lead developer of EasyMock and Objenesis, both of which are projects used by numerous frameworks. Ojenesis is a technical project allowing class creation without calling the constructor. He has also contributed to many Java open source projects. He is currently helping on the JEP 260: Encapsulate Most Internal APIs.

Henri is also the founder of the PerfUG, a user group dedicated to performance. The group currently has more than 400 members. It recently received Java speakers including Kirk, Heinz, Richard Warburton and Jean-Philippe Bempel. He is now involved with the Montreal JUG. 

Henri is a frequent speaker at Java conferences. One of his JavaOne sessions was a hands-on lab with Java champions Heinz Kabutz, Kirk Pepperdine, Ben Evans and Martijn Verburg. Follow him @henri_tremblay

New Java Champion Marcus Lagergren

Welcome the new Java Champion Marcus Lagergren!

Marcus Lagergren has been involved with the Java platform since the alpha versions. He worked at Appeal Virtual Machines, a performance-oriented start-up offering alternatives to byte code interpretation, slow-running thread implementations and non-native code. As one of the principal architects of the JRockit JVM, Marcus helped make sure that Java became a good alternative to writing programs in native languages. 

Marcus contributed to virtual implementations of Java on hypervisors, when virtualization was still in its infancy, and demonstrated with the JRockit VE project that virtual solutions are good alternatives to physical platforms.  

Marcus worked as a member of the Java language team implementing Java 8. He worked on improving support for dynamic languages on the JVM. Being a performance engineer at heart, Marcus demonstrated that dynamic languages, thanks to invokedynamic, achieve similar performance on the JVM compared to languages with a static type system. 

Marcus has co-authored a book on JVM internals, “Oracle JRockit - The Definitive Guide”. He is also a frequent speaker at Java conferences. Follow him @lagergren
