Building objects in the Eclipse IDE is simple - it's a point-and-click solution. However, as applications built on the Eclipse platform mature the need for building outside of the IDE increases. This need can be driven by the development team that is striving to perform agile development techniques where builds are executed based on a file 'check-in' action into an SCM tool. The need can also be driven by IT governance where a scheduled and audited production build is required. Moving from builds managed inside of the Eclipse platform to builds managed outside of the Eclipse platform can be a big task in itself. Don't hesitate to make this jump. It's a jump that you'll find you can't do without. The sooner you get out of your point-and-click build process, the sooner your application will begin to mature.
