    IncompatibleClassChangeError when executed the demo code

      I ran the evaluation/Processtest.java by selecting debug as 'Junit' and I am getting the following error. How can I fix it?

       

      java.lang.IncompatibleClassChangeError: Class org.jbpm.runtime.manager.impl.SimpleRuntimeEnvironment does not implement the requested interface org.kie.api.runtime.manager.RuntimeEnvironment
