Question

We have guice set up as in the documentation and it seems to work fine but we get following error in the application log:

[warn] application – maybe inject.modules config parameter is not set propery?
java.lang.ClassNotFoundException: module.Dependencies

Is that something to ignore? The inject.modules seems to be default value if nothing has been specified in application.conf for inject.modules.

Answer 1

You have to provide a class called module.Dependencies to make the bindings, for instance:

package module;

import com.google.inject.*;
import service.*;

public class Dependencies implements Module {

 public void configure(Binder binder) {
     binder.bind(Service.class).to(SomethingService.class);
  }  
}

Take a look here.
