I just moved from Netbeans to Eclipse. In Netbeans, I can debug Playframework applications out of the box. However, in Eclipse, it seems hard to configure this in order to debug
I guess most of you are running the play framework with Typesafe Activator. If you are doing so, This may help you,
activator -jvm-debug ~run
Like : activator -jvm-debug 9999 ~run
(then It will start the debugger in 9999 port along with the app running in 9000 port.)
