在IntelliJ中运行测试时播放Framework java.lang.NoClassDefFoundError：org / slf4j / LoggerFactory

Question

When i generated the play framework example application (play-java) with activator and imported into IntelliJ everything worked fine and I can run up the application.

I can run the tests on the command line and they all work.

However when I try to run them from the IDE i get the following stack:

java.lang.NoClassDefFoundError: org/slf4j/LoggerFactory
    at play.api.Logger$.<init>(Logger.scala:182)
    at play.api.Logger$.<clinit>(Logger.scala)
    at play.api.Play$.<init>(Play.scala:35)
    at play.api.Play$.<clinit>(Play.scala)
    at views.html.play20.welcome$.apply(welcome.template.scala:18)
    at views.html.index$.apply(index.template.scala:33)
    ...

I'm pretty sure its something simple, but I'm just moving over to Play/IntelliJ from C# so it's not immediately obvious to me!!

Thanks,

Ben

显然，Jar： slf4j.jar由于某种原因未加载。
