--------------------------------------------------------------
I already removed the start.human task from the build.xml, and I received the error I put in the post #1.

I am using the jBPM 5.1 version, and there is no jbpm-human-task-war.war in the deploy folder.
I can see a jbpm-human-task-5.1.0.Final.jar in the WEB-INF/lib directory of the jbpm-gwt-console-server.war, but if I remove this jar, I get the following error

 I would like to understand which is the configuration file that instructs the jbpm console to look for the human task service.
