Hi,

I am getting the exception shown below
SLF4J: See http://www.slf4j.org/codes.html#multiple_bindings for an explanation.
SLF4J: Actual binding is of type [org.slf4j.impl.Log4jLoggerFactory]
Exception in thread "main" java.lang.NoClassDefFoundError: org/activiti/bpmn/model/Task

I did try with 5.11 it is working fine. But when I tried to include 5.12 jars it is giving the error
at             ProcessEngine processEngine = ProcessEngineConfiguration
                  .createProcessEngineConfigurationFromResource("resource/activiti.cfg.xml")
                  .buildProcessEngine();
Tried with 5.12.1 , still seeing the error. Did anyone face the same problem before?

You need to include the acitivit-bpmn-model jars. If you use maven, they are a mandatory dependency and will be fetched automatically.
