Play Framework 2 only recompiles at first request

Question

I am using PlayFramwework 2.1.1 with Scala and I have created a small test server that I run locally (play run from console). If I change something while the server is running, these changes won't be recompiled and "re-deployed" until the first request hits (curl "http://localhost:9000", for example).

Is there a way to have the server refresh upon save, like on Tomcat? Thanks.

Answer 1

Yep. Start it with play ~run. (notice the tilde.) That way, files will automatically be recompiled after saving them.

Answer 2

That's common usage case

play run waits for request to compile changes (so compiles at the first request right after changes)

play ~run after change saving

Keep in mind that goes with price increased memory and CPU consumption, so while developemnt is not always desired situation.
