To many old fashion JDeveloper developers using Maven is a new and obscure thing as JDeveloper has his own build system and does not require ANT or Maven as a build or deployment tool. However if it goes to continuous integration with many small integration automatic builds done daily than using ANT or Maven is inevitable, of which Maven is newer and more popular. Unfortunately for SOA/OSB 12c developers, other popular IDEs, like NetBeans, Eclipse or IntelliJ have much better Maven support than JDeveloper. Still relaying on his old build and deploy system, and using somewhat hybrid approach on integrating Maven, JDeveloper has a lot of issues when it comes to creating new Maven based projects and build them. Moreover Maven problem does not ends with JDeveloper when it comes to proper working of Maven with OSB architecture but it spans whole Middleware architecture.
