I am using guice dependency injection in the simulation class because i need to inject a dependency from a library that i am using. The code looks like:
class AuthenticationServiceSimulation @Inject()(implicit val authenticator: Authenticator) extends Simulation {
val authentication = new Authentication()
and the Authentication class is
@Singleton
class Authentication @Inject()(implicit val authenticator: Authenticator) extends BaseSimulation {
val SERVICE_TOKEN_HEADER = "X-Service-Token" -> authenticator.authManager.buildServiceJwt()
the authenticator class is from the library i am using.
I am able to compile this code but when run, i get a compile time error
