How can I use Eclipse or any other IDE to write the code for plugins? (Or code from the command line?)
Do I need to download Jive files to get started?
Do I need to use Maven, starting here?
Do I need to do that in order to compile a widget and JAR it? Can I just package together my own JAR and compile it from the command line? Especially if I'm doing something as simple as this Hello World tutorial?
