Where to put the external jars? [duplicate]

Answer 1

It doesn't matter too much where you put it, but you need to configure your other non-Eclipse project to put the external jars in its classpath - or use the extensions directory mechanism, if you must. (That's easier, but making it explicit is arguably better.)

Answer 2

I place it into a new folder. This folder has to be included into the build path. It does not matter if it's in Eclipse or outside. Eclipse has a project specific build path and it passes this path to the javac. If you want to execute javac outside of Eclipse, you have to pass the build path manually.

Answer 3

I know this isn't exactly what you are asking, but have you considered using Maven? Some of the plugins like assembly might be helpful in situations like these.
