How do I add Jars to the classpath in Play Framework?

Question

My project needs to use some third-party jars. I assume I drop these in the lib/ directory in my project, but where do I configure Play to add them to the classpath?

I'm developing in Eclipse, and I know I can add them to the Eclipse project's build path, but this won't necessarily make Play reference them when it runs.

Answer 1

Play automatically adds all jars in the application's lib directory to the classpath.

To quote:

A play application classpath is built as follows (in this order):

* The /conf directory for the application
* The $PLAY_PATH/framework/play.jar
* All jar files found in your application /lib directory
* All jar files found in the $PLAY_PATH/framework/lib directory

Answer 2

Do not forget to do a

play ec

or

play eclipsify

when you add new jars in the lib folder. If you don't, Eclipse won't see them.

Play! runtime automatically finds third-parties jars from lib folder so don't worry for runtime.
