I read a bit and found that for some people editing the buils.scala adding the following line inside main helped : ebeanEnabled := true

to me it didnt nither closeing the ide running play clean compile

any ideas???

Answer 1

There is blog post about setting up unit tests to run in IDEs. It suggests to add following command-line to java used when running tests:

-javaagent:/path/to/ebean/ebean-2.7.3-agent.jar

Seems that Play not ships with ebean agent, it should be downloaded from Ebean website first (in main ebean package).

I not tried it.

Ebean user guide also mentions it (15.5.2 javaagent section), there is even example for configuring Eclipse.

Also, to speed up enhancement maybe this will be better:

-javaagent:/path/to/ebean/ebean-2.7.3-agent.jar;packages=models.*

So it will only look into models.* (default package for ORM models in Play).
