I am developing module for using the Quartz scheduler with Spring web application. On startup it gives following error:

Caused by: java.lang.IncompatibleClassChangeError: class org.springframework.scheduling.quartz.JobDetailBean has interface org.quartz.JobDetail as super class
        at java.lang.ClassLoader.defineClass1(Native Method)
        at java.lang.ClassLoader.defineClass(
        at Method)

        at org.mortbay.jetty.webapp.WebAppClassLoader.loadClass(
        at org.springframework.util.ClassUtils.forName(
        ... 65 more

I am using maven for this project.

How to resolve this error?
