I've been researching this for a while but I have to ask: isn't it accomplishable through Eclipse by now? I've found answers regarding Maven and Ant, but I've never used either. Should my output .jar file be a runnable jar it could be done through eclipse, but it's a library that uses external jars.
So, is there something I missed or it is the Maven/Ant path for me?
Edit: regarding Jarrod answer, I'm on a tight schedule here and can't afford spare much time on this task (thanks for the tip, 'tho!)
