Error when adding the Swagger library

[Pesia Soloveichik]

I'm using Java Play 2.5 and I'm trying to add the Swagger plugin to my project.

In build.sbt I added the following code:

libraryDependencies += "io.swagger" %% "swagger-play2" % "1.5.3"

In application.conf I added the following:

play.modules {
  enabled += "play.modules.swagger.SwaggerModule"
}

Then I ran "sbt clean compile" - It compiled successfully.

But when I try to use it in my code:

import io.swagger.*;

I get the following error:

"error: package io does not exist"

Any idea how to solve that?
