Building DTF In Eclipse

Building under Eclipse is as easy as right clicking on the build.xml file at the root of the project and then selecting Run As -> Ant Build and that will automatically run the build target. Then after that if you want to customize the the targets executed you'll have to click on the menu Run -> External Tools -> External Tools Configurations... in the next window you'll be able to customize which targets to run and in which order. I usually set this to run the clean target followed by the build because I like to make sure I have a nice clean build every time.
