now you need to choose depending on the transport that you want to use.
If you are planing to use a local task service you just need to include <artifactId>jbpm-human-task-core</artifactId>
if you wanna use Mina, HornetQ or JMS you will also need to add:
<artifactId>jbpm-human-task-mina</artifactId> -> for Mina
<artifactId>jbpm-human-task-hornetq</artifactId> -> For hornetQ
<artifactId>jbpm-human-task-JMS</artifactId> -> for JMS
PS: please mark all your answered questions as answered
