I created a new project and working with eclipse (used eclipsify command).
basically, I moved the app directory from an old project to the new one I created.

the problem is that eclipse doesn't recognize the views. I get errors like:

views.html.viewTopic cannot be resolved to a type

I tried to play compile but it didn't help.
so I got 40 errors. all of them connected to the fact that the views aren't compiled and therefore, the eclipse doesn't recognize them (my guess of course).

what can I do?
by the way, the old project compiled and ran without a problem (I used intellij)

    Also, make sure Eclipse is refreshing filesystem changes automatically. See: http://scala-ide.org/docs/tutorials/play20scalaide20/index.html ("Configure Eclipse so changes on the file system are automatically picked up") – Andrew Conner Sep 21 '12 at 12:29

For Java Play Framework v2.4.6 (activator v1.3.7) with Eclipse Mars:

So that you will not have a "can not resolve error" with your viewTopic.render(), you can add this <classpathentry kind="lib" path="target/scala-2.11/classes"/> to your .classpath or right-click on your project -> Build Path -> Configure Build Path -> Add Class Folder and make it point to target/scala-2.11/classes.

  • Run 'play eclipse' on the command line
  • In Eclipse, refresh your Project via hitting F5

Re-run the command in play console with the sources this time:
$ eclipse with-source=true

And then go to eclipse and clean your project and build all

According to jetbrains, the issue with templates is fixed. If you have play 2 generated source sources included in the IDEA project then you should exclude this folder from the project

http://www.jetbrains.com/idea/webhelp/configuring-folders-within-a-content-root.html

and do File | Invalidate caches and restart.

If you have an SBT project, open it in IDEA via File | Import Project | Sbt type project

Make sure to use the latest Scala and Play 2 plugins.

  1. Close eclipse project
  2. activator eclipse
  3. activator compile
  4. Open eclipse project
  5. Add target/scala-[your-version-here]/classes to your build path as a class folder

The best you can do is just search the Stack Overflow as this topic was discussed really many times.

  • ok, I've seen something strange. in `src_managed` directory there is no `models` directory although there should be. there's only `controllers` and `views`. why is that? – socksocket Sep 21 '12 at 13:22

    Did you check what `controllers` and `views` contains? most prbably in first you have only `routes.java` - in second html files compiled into scala functions. There are no controller's or model's classes, so yes it looks normal. – biesior Sep 21 '12 at 13:38
  • I run the command `play idea` and now using intellij but still, same problem. intellij does not recognize those views.html files. – socksocket Sep 21 '12 at 13:50

    Really strange, I'm working with Idea and it recognizes views just view seconds after recompiling – biesior Sep 21 '12 at 13:57
  • this is what I did. I created a new project. after that, I copied an old `app` directory (with all the sub-dirs - views, models, controllers). I compiled and ran the project. very strange indeed... – socksocket Sep 21 '12 at 14:56

OK, I solved it.

  • I created a new app again
  • moved app dir
  • only then ran the command play idea
