I’m trying to figure out the proper tools for managing dependencies between JARs. I have a Play Framework app, which imports a JAR (based on another project I’m writing). This JAR imports other JARs, some of which have dependencies for yet other JARs.

This far, I’ve gotten by with adding stuff to the build path in Eclipse. But when I deploy the Play app (export to .war, deploy on Glassfish), the necessary JARs are not included. I need to manually copy these into play/lib. Which is a pain since they are so many.

So my question is two-fold:

  • For the JAR file I’m writing: what’s a better way of managing the dependencies? Maven?
  • For the Play app, is there some way of avoiding copying stuff into /play/lib, and still be able to deploy without pain?

In the ideal scenario, I would like to import a completely self-contained JAR-file into the Play app, i.e. I don’t need to add the JAR-file’s dependencies to play as well. How can I achieve this?

Thanks in advance.

    Here is the easiest way to achieve what you want:
    http://www.playframework.org/modules/ivy
    (and you can combine it with IvyDE, an Eclipse plugin for managing dependecies with Ivy)
