Question

Finding hard to know why am I unable to get this thing :

… I can run my application from command prompt, But when I do idea and Import the existing project using IntelliJ unable to trace out what Libraries or Jar files I need to get going.

In one Play1.2.3 I used to just Import Play and Play1.2.3 jar files and everything works..

Update

Have tried Creating a new project and Open Project(Instead of Import) from IntelliJ,But no luck.It has attached all the Libraries but still the error doesnt go screenshot attached:

IDE :IntelliJ 11.0.2 &
Play : 2.0.2

Answer 1

Since Play 2.0.2 you don’t need to create Idea’s project from the scratch and import modules into it.

Just choose Open project from the menu, and find the folder where you performed play idea action, whole project will be ready to use in the IDE without any additional steps.

Edit:

Most important: to reflect changes in managed sources your application need to compile it first, so it needs to work in the background while developing or you need to compile it manually if app is stopped. Otherwise Idea will not be able to compile (and find) managed sources. That’s exactly job of the Play’s DEV mode which differs from others Java frameworks, which requires to compile app manually and/or configuring your IDE to do that from time to time. Play’s dev mode allows to do it in background.

Idea will start recognizing your managed sources after first run the app in the browser (as it will compile it, and idea will catch it just few seconds later). Of course the app must be running in dev mode, to compile views, assets etc.

play run

Of course if you’re in production mode, you also need to restart the app.
alternatively after idealizing the project, or if your app is not working you can manually compile managed sources with:

play compile

Also if you’ll start in tilde-dev mode, it will be compiling changed resources right after the changes’ saving

play ~run
