OpenFL is designed to be built from the Lime command-line tools, so it is much more than a “haxe build.hxml” step (which the normal FlashDevelop template might use), since we generate icons, embed SWF assets, copy and rename assets, precompile and compile binaries and other steps needed for all the platform targets.

openfl create project MyNewProject
openfl test flash
