Hi Ankit, expanpe-t5-lib seems to be for Tapestry 5.3 and should have stopped working with 5.4+ because Javassist and related code was removed/replaced.
You could check out org.apache.tapestry5.services.transform.ComponentClassTransformWorker2 and its implementations on how to similar tasks like fr.exanpe.t5.lib.internal.contextpagereset.ContextPageResetWorker But adapting the dependency might be quite some work, especially if you're not familiar with "plastic" (Tapestry class/method/proxy generation et al.) Depending on how much you need from the dependency, vendoring only the required parts may be an easier approach.
