Using gradle for dependency managment

Question

I am trying to use gradle only for the jar dependencies, meaning that I took all the jars from the build path and wrote it like this:compile 'groupid:artifactid:version'.

Now when I am trying to run the server (tomcat 7.0.39) I get this:

java.lang.IllegalStateException: Second notification for the same phase in the same request occurred. phaseId.ordinal: 1; phaseId = RESTORE_VIEW 1; More than one org.openfaces.component.validation.ValidatorPhaseListener is found to be registered (2). Check that only one JSF implementation is deployed with your application's classpath, and openfaces.jar is not duplicated in application's and server's libraries.

I don't understand what am I supposed to do and where to look.

Can someone shed some light?

What you need to do is to run gradle dependencies to view the dependency tree. Then search for the problematic packages - it should be doubled. You need to exclude one of the conflicting packages. Here're a docs on dependencies exclusion.
