For building Play 2.0 I followed this recipe (beware - bleeding edge ;-)
$ git clone git://github.com/playframework/Play20.git
$ cd Play20/framework
$ ./build publish-local
$ PATH=$PATH:Play20
In an Eclipse Workspace:
$ play new test20
$ cd test20
$ play eclipsify
$ play ~run
In Eclipse:
- Preferences/General/Workspace: Enable "Refresh using native hooks or polling"
- File/Import.../General/Existing projects into workspace...
It doesn't work for me. eclipsify is not recognized as a valid command... That's why is use the eclipse sbt plugin from Typesafe : https://github.com/typesafehub/sbteclipse
Sorry to hear that, but... Are you sure you are using github head? - eclipsify was not included in the public beta, but is available in head. I just check the commands I gave and they worked for me...
But alas, as of today, classes generated from scla templates are no longer written to classes_managed if a compilation error occurs. So errors currently are again not automatically shown in Eclipse.
