Mailer plugin does not appear in applications

Question

I am trying to use the Mailer plugin in my game! 2 Java applications.
I followed the instructions in the Readme file, but the module does not appear in my applications. So when I try to compile it, play it! gives me an error:

object plugin is not a member of package com.typesafe 

I tried reloading the project and double checking the files in /project . So far nothing has worked.

Is there any way to make it play! to check application dependencies?

Update:

Ok, new error message. I deleted /project/project/ , /project/target/ and /target/ . Next time I started to play! It took quite a while to get all the modules. He did not download the Mailer plugin.
But now I get:

 play.api.PlayException: Cannot load plugin [Plugin [com.typesafe.plugin.CommonsMailerPlugin] cannot been instantiated.] 

and then:

 Caused by: java.lang.ClassNotFoundException: com.typesafe.plugin.CommonsMailerPlugin 

Any ideas?

Update 2:
Ok, I fixed this by downloading play-plugins-mailer_2.9.1-2.0.4.jar directly from typesafe and placing it in /lib . This is definitely not the right way, but at least now it works. I needed my game! 2.0.3: http://repo.typesafe.com/typesafe/releases/com/typesafe/play-plugins-mailer_2.9.1/2.0.4/

Answer 1

Good to play! To manage my dependencies, I had to create a new copy of the project on top of the old files (excluding the already compiled code), edit Build.scala and reload / compile the project inside the game! console.
Now it works! The Mailer plugin is loaded, compiled and play dependencies lists it.
