Added few more bpmns with different id's offcourse and with different version on asset artifact and deployed it.

I am pretty sure nothing has changed incode.

One more thing i checked in deployement store table after each deployment i am getting one entry added so deployment is successful.

Update:

When i tried to deploy and start older asset artifacts i am able to do successfully.

I mean version 1 is getting deployed as well as started.

but

version 2 is deployed but not started with above exception.

Only change i did was added same jbpmn file twice with different name and precess id and added jbpmn drools task in one of them.

Does it makes any difference?
