In my organization we have several projects that were developed to be built by older versions of Maven (e.g. 2.0.x, 2.2.x). Our new projects are now developed to be built by Maven 3.0.x, but the older projects don't always build properly under 3.0. The IDE provides the ability to switch to different versions of Maven, but this setting is applied globally, so it becomes tiresome and unproductive to have to change this setting every time I go to build a project that needs a different version of Maven. NetBeans needs to provide the ability to identify which instance of Maven to use for building each project.
