Q:

Issue with maven ant plugin for generating hbm files in hibernate using Xdoclet

I am trying to generate hbm files using ant task with maven, however it's running into issues related to classpath. (I am doing this to migrate the project from ant to maven and do not want to change the way hibernate works in the first step). If someone knows a better way to handle this, that would also be helpful. My pom.xml looks like

The exception that I am getting is 
   Can't create a hibernate element under hibernatedoclet. Make sure the jar file containing    the corresponding subtask class is on the classpath specified in the <taskdef> that defined {2}.

A:

As the error says

Can't create a hibernate element under hibernatedoclet

I guess you need to add hibernate to your maven ant plugin dependency.
